A New Headquarters and a New Museum

The year is 1935. The U.S. Department of the Interior is growing in its responsibilities yet has outgrown its existing WWI-era headquarters building. Thirty-second Secretary of the Interior Harold L. Ickes (1874–1952) undertakes the ambitious endeavor of creating a new headquarters. Federal Public Works Project No. 4 becomes the first federal building in the nation’s capital to be authorized, planned and constructed under President Franklin D. Roosevelt’s administration. From the outset, the building is to embody the principles of utility and economy: “a new deal for a new day.”

Secretary Ickes realizes that the Interior Department is a large, complex federal agency difficult for the public to understand. He views the construction of the new headquarters as an opportunity for the Department to be more transparent and relevant to the American people. Consequently, the building is very intentional in terms of its design and what it will include.

One of several elements Ickes specifies is a museum that will present the story of the Department and educate the public. It will join some 67 other museums nationwide within the Department’s National Park Service but will be just the twenty-third museum in Washington, D.C.—and unique in a Cabinet-level agency as a “new instrument in the field of government public relations.” To this end, Ickes establishes a museum planning committee. By May 1935—just as initial construction is beginning on the headquarters itself—the Public Works Administration (PWA) allocates $100,000 for the Interior Museum.

The Eastern Museum Laboratory at Morristown

The National Park Service recruits Ned J. Burns (1899–1953) to be the superintendent of its newly-established Eastern Museum Laboratory in Morristown, New Jersey. Burns comes on board in June 1935 and is immediately tasked with making the Interior Museum a reality. By July, four curators are busily developing detailed exhibit outlines and identifying possible artifacts. By early autumn there is both a conceptual scale model . . .

. . . and a much larger one, so the exhibit fabricators at Morristown can better visualize the unbuilt gallery space. Come September, Burns is already beginning to translate the curators' ideas into physical exhibition components.

Having gained extensive experience at the City Museum of New York and the American Museum of Natural History, Burns is an acknowledged expert in exhibition design. By the end of 1935 Burns has assembled at Morristown a skilled team of 21 to work on Interior Museum exhibits: 12 preparators, 3 per diem carpenters, 3 per diem helpers, a field curator, an equipment engineer, and a clerk.

Life size ethnological displays and habitat groups of exotic taxidermy had featured in natural history museums since the late 1800s, but it is not until the 1920s that miniature groupings or dioramas truly gain in popularity. Deriving from the Greek meaning literally “to see through,” dioramas are essentially shadow box models—usually on a scale of 1 1/2 inches equaling 1 foot—viewed through an angled, polished glass aperture. The three-dimensional scene in the foreground blends seamlessly into a scenic perspective painted onto a curved background. Illuminated from above through a filter of sandblasted glass, the overall effect gives the illusion of greater depth.

Burns has previously employed dioramas to great success and therefore envisions creating several for the new Interior Museum. He appreciates that dioramas can convey considerable information in relatively little space and would later say:

The true worth of the miniature lies in its power to tell a vital story in a dramatic way, through its inherent attractiveness and appeal to the imagination. . . . This irresistible appeal . . . is universal in all of us who, as children, delighted in the toys with which we built our own miniature worlds. By taking advantage of this fundamental human psychology we are enabled to convey our museum story in a pleasant, yet equally effective and long-remembered way.

That the Interior Museum contains so many dioramas provides us an unusual wormhole to the past. They represent an era of rapid development and adaptation in museum interpretation and are particularly notable for their craftsmanship. More broadly, the dioramas are emblematic of an increased professionalism and focus on the visitor experience.

What follows is an in-depth exploration of the creation of 13 dioramas. The first 11 are purpose-built for the Interior Museum in anticipation of its inaugural exhibitions opening in March 1938. The remaining two are added to the Museum's displays in 1940 and 1945.

Diorama: "Washington and Lafayette in Morristown, New Jersey, 1780" (1935/1936) by National Park Service, Eastern Museum Laboratory, Lee Roland Warthen (1893-1949), Rudolf W. Bauss (1899-1966), Basil E. Martin (1903-1988), and Rosario Russell Fiore (1908-1994)U.S. Department of the Interior Museum

Washington and Lafayette at Morristown, New Jersey, 1780

This diorama depicts the scene at Ford Mansion in Morristown, New Jersey, when General George Washington greets the Marquis de Lafayette on March 10, 1780. Morristown is nationally significant as being the location of the Continental Army's 1799-1780 winter encampment under the command of General Washington in the American Revolutionary War. The Marquis de Lafayette had personally come to inform Washington that France would be sending not only a large fleet of ships but also trained soldiers to aid the Continental Army. It was a commitment that ultimately played an important role in securing American independence. Today, the site is operated by the National Park Service as Morristown National Historical Park. 

Landscaping the "Morristown" diorama (circa 1936) by National Park Service, Eastern Museum LaboratoryU.S. Department of the Interior Museum

Work begins on the Washington and Lafayette in Morristown diorama sometime during the last half of 1935. It is believed to be one of the first undertaken by the National Park Service's Eastern Museum Laboratory (EML) for the Interior Museum. EML’s close proximity to the historic Ford Mansion makes for easy reference and allows the preparators to be especially accurate in rendering the landscape and architecture.

Shown here is Rudolf W. Bauss (1899–1966) who came to the EML as a skilled model maker. He had previously served a full apprenticeship in Germany as a furniture woodcarver.

Two dioramas depicting Morristown, New Jersey (circa 1936) by National Park Service, Eastern Museum LaboratoryU.S. Department of the Interior Museum

Preparators ultimately create two Washington and Lafayette in Morristown dioramas: one for New Jersey's Morristown National Historical Park (established as the nation's first National Historical Park in 1933) and one for the Interior Museum to open in Washington, D.C., in March 1938.

Here, Lee Roland Warthen (1893–1949) is painting the backgrounds. He is a prolific artist and illustrator who works extensively on the Interior Museum, contributes to countless other National Park Service museum displays, and goes on to do design work for the Navy and Army.

"Morristown" wax figures (circa 1936) by National Park Service, Eastern Museum LaboratoryU.S. Department of the Interior Museum

Basil E. Martin (1903–1988) attends to the finish work on this diorama's figurines. Most of the figures in these early Interior Museum dioramas are sculpted by Rosario Russell Fiore (1908–1994) who had trained at New York's National Academy of Design.

They are constructed by modeling hard wax onto wire frameworks. While clothing is typically sculpted as part of the wax, it is sometimes fashioned separately from leather or silk. For this diorama, Fiore is provided with detailed research on the uniforms and how the Continental Army’s differed from those worn by General Washington's personal guard.

In later dioramas, the figures are created by pouring wax (and later, plasticene) into plaster molds.

The small accessories in a diorama are made from a variety of woods, plastics and metals. Tools of the trade for creating these intricate miniature replicas include calipers and tiny chisels.

Note the detail on the rifles, swords, and door handle for the Washington and Lafayette scene.

Diorama: "Fort Union Trading Post, 1835" (1935/1936) by National Park Service, Eastern Museum Laboratory, Rosario Russell Fiore (1908-1994), and Frank G. UrbanU.S. Department of the Interior Museum

Fort Union Trading Post, 1835

This diorama showcases the main gate at Fort Union Trading Post, circa 1835. Operated as a privately-owned commercial establishment on Assiniboine tribal land in what is now North Dakota, it was the most important and profitable fur trade post on the Upper Missouri River in the years 1828 to 1867, averaging $100,000 in merchandise sales annually. Seven Northern Plains Indian tribes peaceably interacted here to exchange buffalo robes and smaller pelts for goods from around the world.  

Early Construction on the "Fort Union" diorama (1935/1936) by National Park Service, Eastern Museum LaboratoryU.S. Department of the Interior Museum

The Fort Union Trading Post diorama is specifically created for display in the Indian Affairs alcove within the Interior Museum. Preliminary research in 1935 involves consulting numerous historical accounts of the trading post, as well as George Catlin's portraits of North American Indians. Construction on the diorama commences in February 1936. Frank G. Urban, pictured here, is completing some of the structural groundwork.

Sculptor Rosario Russell Fiore (1908–1994) and Frank G. Urban (right) stand before the incomplete Fort Union diorama, most likely in the summer of 1936. Chief Preparator Arthur Jansson's painted background already appears to be finished. To ensure the mural's accuracy, Jansson had requested information about Mackinaw boats and asked that the U.S. Geological Survey confirm the "color of the bluffs on the south bank of the Missouri River, about on the State line between North Dakota and Montana."

This tiny lantern is an example of the precise craftsmanship that went into creating the dioramas. Can you spot this same lantern in the Fort Union diorama? Hint: it is hanging by the doorway.

Diorama: "Camping at Yellowstone: Birth of the National Park Idea, 1870" (1935/1936) by National Park Service, Eastern Museum Laboratory, Albert McClure (1903-1986), and Lee Roland Warthen (1893-1949)U.S. Department of the Interior Museum

Camping at Yellowstone: Birth of the National Park Idea, 1870

This diorama is significant for its pictorial representation of a key moment in National Park Service history. On September 19, 1870, members of the Washburn-Langford-Doane Expedition gathered around a campfire near Madison Junction—where the Firehole and Gibbon rivers join to form the Madison River. The group discussed the wonders they had seen and collectively agreed that the northwestern Wyoming landscape should be preserved as a public park. This proposal contributed to a groundswell of support for creating national parks. Ultimately, a year and half later, the United States Congress passed an act establishing Yellowstone National Park. It was signed into law by President Ulysses S. Grant, making Yellowstone the first national park not only in the United States but in the world.

Like the Washington and Lafayette diorama, this one is made for the National Park Service’s alcove within the Interior Museum. Albert McClure (1903–1986) is shown here recreating the Yellowstone landscape at the Morristown laboratory in spring/summer 1936.

Groundworks for the dioramas are usually modeled with composition board, plaster and papier-mâché. Trees, too, are often papier-mâché, with the foliage crafted either from paper or metal and then affixed with fine wire.

An artist—believed to be Lee Roland Warthen (1893–1949)—paints a forest onto the jagged backdrop cutout. In the finished diorama, three-dimensional miniature trees are placed in front of the painted ones to create a realistic sense of depth and perspective. Note the reference photographs in the foreground of this image.

To lend further authenticity to the scene, the fabricators verified details with preeminent artist and photographer William Henry Jackson (1843–1942). He had camped in the Yellowstone region as part of the 1871 Hayden Expedition just one year after the 1870 Washburn-Langford-Doane Expedition depicted in the diorama.

These are nine of the 12 figurines appearing in the Birth of the National Park Idea diorama. They represent some of the explorers in the Washburn-Langford-Doane party. The man standing with his arm outstretched is one of the civilians on the expedition, Judge Cornelius Hedges (1856–1907) from the Montana Territory.

Diorama: "Land Office, Guthrie - April 1889" (1935/1936) by National Park Service, Eastern Museum Laboratory, Donald M. Johnson, and Arthur A. Jansson (1890-1960)U.S. Department of the Interior Museum

Land Office at Guthrie, April 1889

To accommodate the rapid growth of public lands previously handled by the Department of the Treasury, the U.S. Congress established the General Land Office (GLO) in 1812. Oversight of the GLO transferred to the Department of the Interior upon its creation in 1849. The GLO’s responsibilities included surveying public lands, managing such issues as land sales and patents and—with the Homestead Act of 1862—acting as the administrator of homesteads. The Homestead Act opened vast tracts of the public domain, giving settlers the opportunity to receive title to up to 160-acre plots, provided that they made a five-year commitment to build a residence and grow crops on their claim. This diorama was created in 1935-1936 to highlight one aspect of GLO history in its alcove within the Interior Museum. The scene illustrates the flurry of activity at the Land Office in Guthrie, Indian Territory (now the U.S. state of Oklahoma) in the days immediately following the opening of two million acres to homesteaders at high noon on April 22, 1889. An estimated 50,000 people turned out to lay claims. Spectacular tent cities like this one would spring up literally overnight in response to a land rush.

Artist Arthur A. Jansson (1890–1960) paints the features that contribute to the realism of the Land Office diorama. Jansson had formerly painted life-size backdrops for the habitat groups at the American Museum of Natural History in New York City, the Academy of Natural Sciences in Philadelphia, and the Smithsonian's National Museum of Natural History.

To convey the excitement and activity evident in the scene, museum technicians consulted historical photographs and even corresponded with Fred L. Wenner, a former newspaperman who had been an eyewitness to this very land rush reporting on “that and all the other stirring events of the early days of Oklahoma.”

Donald M. Johnson positions the painted wax figurines in the Land Office diorama. Johnson had studied art at the Pratt Institute. Prior to joining the National Park Service's Eastern Museum Laboratory, he had worked for many years creating dioramas at the Museum of the City of New York.

Diorama: "Coal Mine Explosion" (1935/1936) by National Park Service, Eastern Museum Laboratory and Albert McClure (1903-1986)U.S. Department of the Interior Museum

Coal Mine Explosion, 1929

More than 80 mine explosions within a period of five years led to the creation of the U.S. Department of the Interior's Bureau of Mines in 1910. Originally charged with ensuring safer mining practices and equipment, the Bureau quickly expanded its mission to include the more efficient use of minerals. When the Interior Museum opened to the public in 1938, an alcove dedicated to the history of the Bureau of Mines included this diorama. The disaster scene is from a real-life incident that occurred on March 21, 1929. A spark from a piece of machinery in the Kinloch Mine in Parnassus, Pennsylvania, caused an explosion, killing 52 coal miners and entombing more than 200. The trapped miners were eventually rescued via an unused entry five miles from the main shaft.

Striving for authenticity in the Coal Mine Explosion diorama, the model makers begin in 1935 by securing press images like this one of the accident site . . .

The figures are rendered with particularly lifelike expressions and poses. Some of the onlookers are obviously distraught. A uniformed official keeps the bystanders from descending into the disaster area, while in the background, workers disembark from a train marked "BUREAU OF MINES" to help with the recovery efforts.

Diorama: "Geological Survey River-Measurement Station" (1935/1936) by National Park Service, Eastern Museum Laboratory, Rudolf W. Bauss (1899-1966), and Arthur A. Jansson (1890-1960)U.S. Department of the Interior Museum

Geological Survey River-Measurement Station

Requisitioned in October 1935, this diorama at 1.5”=1’-0” scale was completed in
1936 for the U.S. Geological Survey’s exhibit alcove within the Interior Museum.
While the diorama is intended to typify stream-gauging activities at any U.S.
Geological Survey (USGS) measurement station in the early 1930s, this scene is
at least somewhat based upon the Hackensack River in New Jersey. This diorama differs from its contemporaries in that not all the
components were fabricated by the National Park Service’s field laboratory.
John Hoyt, a hydraulic engineer with USGS, supplied the cable car and meter.  

The tower serves as the gauge house. In practice, a pipe connects directly to the river and contains a water-stage recorder which makes continuous readings of the height of the water.

The man in the cable car suspended above the river . . .

. . . takes current-meter measurements of discharge. The measurements are then used to help compute a river’s daily flow rate, a useful indicator when making predictions and decisions about water supply.

Here, Rudolf Bauss (1899–1966) sculpts the automobile for the River-Measurement Station diorama. USGS Hydraulic Engineer John Hoyt sent Bauss a USGS license plate and automobile seal to replicate to scale, so the car would be as faithful a representation as possible.

Rudolf Bauss assesses progress on the diorama. He has placed the completed automobile in the scene but has yet to add the two figurines. The painted background and technical details—down to the precise wording on the tower sign—were informed by a series of photographs, pamphlets, blueprints and sketches supplied by USGS Hydraulic Engineer John Hoyt and O. W. Hartwell, a district engineer based in Trenton, New Jersey.

Irrigation of a Cotton Field, 1930s

In March 1936, preparators at Morristown start on another diorama slated for the U.S. Geological Survey (USGS) alcove in the Interior Museum. The purpose of this one is to emphasize the USGS’s recent work in New Mexico’s Roswell Artesian Basin. Hydrologic investigations of the Basin had originated in 1906, and a more comprehensive study conducted in 1933 confirmed that the Basin was indeed a world-class example of a rechargeable artesian aquifer system. Based on these findings, the USGS made recommendations to the State Engineer for making the aquifer even more sustainable. Despite long, hot summers with scant annual precipitation, the Roswell Basin efficiently derives water for irrigating crops almost exclusively from the groundwater supply and, to this day, remains among the most intensively farmed regions in New Mexico.

The Roswell Chamber of Commerce also sends photographs, including this one of a Roswell farm house, circa 1935. The farm depicted in the resulting diorama seems to be a compilation of several different locales.

Landscaping the "Irrigation of a Cotton Field" diorama (circa 1936) by National Park Service, Eastern Museum LaboratoryU.S. Department of the Interior Museum

Considerable research and critical review goes into ensuring the historical integrity of the dioramas. For example, a memo regarding the design of Irrigation of a Cotton Field includes the following direction:

"As cotton is a very characteristic crop of the Roswell area and is grown on about 50 percent of the area that is under cultivation, it would seem to be an especially appropriate crop to be shown in the foreground. Furthermore it is understood that it can be reproduced rather realistically, showing the cotton in the boll stage. However, as cotton in the boll stage is not generally irrigated, it will be necessary to direct the flow from the well—probably to the rear of the diorama—and show the water being run on an alfalfa field as this crop is irrigated until early fall. Another crop that might be considered in this connection is that of corn, as this crop can likewise be reproduced in miniature to good advantage."

All three crops—cotton, alfalfa and corn—are evident in the finished diorama.

Diorama: "Kettleman Hills North Dome Oil Field, California" (1935/1936) by National Park Service, Eastern Museum Laboratories, Donald M. Johnson, Rudolf W. Bauss (1899-1966), Arthur A. Jansson (1890-1960), and Albert McClure (1903-1986)U.S. Department of the Interior Museum

Kettleman Hills North Dome Oil Field, circa 1935

Curatorial plans called for three dioramas in the inaugural exhibits for the U.S. Geological Survey (USGS) alcove within the Interior Museum. While a September 1935 report issued by the Morristown team specifies the "River-Measurement Station" and "Irrigation of a Cotton Field" dioramas, the site to be depicted in this third diorama remains unidentified, stating only that it is intended to show the “unit plan operation of an oil field.” Yet by October, the decision is made to replicate a contemporary scene at Kettleman Hills North Dome, an oil field spanning California's Kings and Fresno counties. Seven years earlier—on October 5, 1928—the Milham Oil Company had discovered large oil and gas reservoirs there at a depth of 7,108 feet.

At the time of this diorama’s construction in 1935-1936, the USGS is supervising “efficient oil and gas production from leased public lands,” and Kettleman is one of the largest and most productive oil fields in the country.

The field would yield more than a half billion barrels of oil and 2.5 trillion cubic feet of gas in the ensuing decades. Today, less than half of one percent of the original oil remains at Kettleman.

Preparators like Rudolf Bauss utilize many primary sources to aid their work on the dioramas.

W. P. Woodring, a USGS geologist well-versed with the Kettleman region, supplies the Morristown designers with relevant geological and topographical maps, as well as photographs, postcards, panoramic views, and technical books on petroleum production engineering.

Here, an artist believed to be Lee Roland Warthen (1893–1949), incorporates some of that visual material into the painted backdrop for Kettleman Hills North Dome.

This photograph imparts just how involved the dioramas are. Donald M. Johnson (left) and Albert McClure (right) lend a sense of scale to Kettleman Hills North Dome. While visitors will view this completed scene through a relatively small, framed glass front, the infrastructure needs to be much larger to accommodate the lighting effects and curved backdrop that create the proper perspective. Overall, the outer shell of this diorama measures more than two feet deep and six feet square!

Diorama: "Boulder Dam" (Hoover Dam) (1935/1936) by National Park Service, Eastern Museum Laboratory, Donald M. Johnson, Frank G. Urban, Lee Roland Warthen (1893-1949), Ned J. Burns (1899-1953), and Lynn A. RoyalU.S. Department of the Interior Museum

Boulder Dam (Hoover Dam), 1935

On July 4, 1930, Department of the Interior secretary Ray Lyman Wilbur authorized the preparatory work needed for building Hoover Dam on the Colorado River, straddling the Arizona-Nevada State line. The creation of Boulder City, transmission lines, infrastructure, a cableway, and the extension of a railroad route began in earnest. Construction on the dam itself commenced in 1931, ultimately employing more than 21,000 workers in the midst of the Great Depression. Under President Franklin D. Roosevelt, the project was referred to simply as "Boulder Dam"—a political renouncement of its origins in the Hoover Administration. With Boulder Dam—destined to temporarily be the tallest dam on the planet—came the promise of the Interior’s Bureau of Reclamation irrigating millions of arid acres, generating electricity, and contributing to the rise of major cities in the West. When in August 1935 it is time to requisition a diorama for Reclamation’s exhibit alcove in the Interior Museum, a scene of Boulder Dam is the obvious choice. At the dedication ceremony for the real dam just a month later (September 30, 1935), Interior Secretary Harold Ickes calls Boulder Dam* an “imagination-stirring project that in grandeur, conception and in skill and speed in execution ranks as one of the greatest engineering undertakings in the history of the world.” The dam as a diorama will reinforce this notion, inspiring visitors with its beauty and utility.                                                                                                                                                                                    *(The name of the dam was officially restored to "Hoover Dam" in 1947.)

To assist the diorama designers, the Bureau of Reclamation sends engineering drawings, maps, sketches and more than 50 photographic prints of the dam, permanent cableway, control house, anchorage, spillway, parking area, and the power house and intake towers on the Arizona side.

Inspecting the "Boulder Dam" diorama (1936) by Morristown Field Laboratories and Eastern Museum LaboratoryU.S. Department of the Interior Museum

. . . here conversing with Ned Burns (left) about the diorama. Burns is a stickler for details, and even though Reclamation officials provided information early on about the color and composition of the canyon walls at the dam site, Burns requests a second opinion. On November 23, 1935, Burns write to his superior, Dr. Carl P. Russell:

“Some questions have arisen regarding the rock color of Bowlder [sic] Dam. Information to date has been that the rocks are black. It has occurred to me that all this was gained from engineers and other observers who are not artists. After the rock [in the diorama] is once colored it will be difficult to change it, and if possible, we should be sure before coloring it. . . . Perhaps you may think me rather fussy on this point, but past experience in making museum exhibits has taught me to be very careful with such details. The public loves to criticize, so if you get the opinion of an artist, it would be safer.”

A progress report issued in March 1936 about the Interior Museum states that the Boulder Dam (Hoover Dam) diorama is nearly done. Its dimensions are 7’ 6” x 4’, with the viewing opening 5’ wide by 3’ high.

Window Rock, circa 1936

Space is allocated in the Indian Affairs alcove of the Interior Museum for two dioramas. The initial September 1935 set of planning documents indicates a historical scene, e.g. the "Fort Union Trading Post" diorama, with the other left unspecified but envisioned as showing “life on a modern reservation.” A revised plan issued in February 1936 stipulates the contemporary setting to be Pine Ridge Indian Reservation in the South Dakota, stating that this diorama will, “portray as realistically as possible the life on a typical Indian Reservation today. The majority of visitors to the Interior Museum will probably never have seen an Indian Reservation and this carefully constructed miniature will be of great value in enabling them to obtain a comprehension of what modern Indian life is like.”



By May 1936, however, further refinements to the exhibit plan result in a decision to switch the diorama to instead depict a Southwest scene of the newly established capital of the Navajo Nation at Window Rock, Arizona. John Collier, the Department of the Interior’s 33rd Commissioner of Indian Affairs (1933-1945), had recently selected Window Rock for the Navajo Central Agency Headquarters, consolidating what had previously been scattered across the existing Navajo reservation.

Research ensues.

The U.S. Indian Service provides this image to the designers. It shows one of the Navajo Central Agency administrative buildings newly constructed in 1936 from locally-quarried sandstone. This photo clearly impacts the perspective and orientation of the completed diorama . . .

. . . since this very scene appears on the painted background at the right, somewhat obscured by the vertical loom. The landscape’s signature feature, the perforated “Window Rock” (Tségháhoodzání in Navajo), is clearly visible.

Several other structures are painted in as well—likely including the Public Health Service dispensary, the Council House, the Department of the Interior's Indian Affairs office, a school, employees’ quarters, and utility buildings.

The southeast-to-northwest vista in the diorama means that the opening to the Navajo hogan faces east, as would be customary.

Activity in the foreground tells of contemporary Navajo domestic life of the mid 1930s. Men and women are working at food preparation, silversmithing, and weaving.

The diorama was completed in late 1937.

Diorama: "Grazing on the Public Domain" (1936/1937) by National Park Service, Eastern Museum LaboratoryU.S. Department of the Interior Museum

Grazing on the Public Domain

The inspiration for this diorama was the passage in 1934 of the Taylor Grazing Act (Public Law 72-482). Signed by President Franklin D. Roosevelt, the Act sought to prevent overgrazing and soil deterioration as well as stabilize the livestock industry dependent upon public lands. 

Gavel and sound block (1939)U.S. Department of the Interior Museum

The deterioration of rangelands had become a serious issue by the 1930s. As the country expanded westward, the number of sheep had already quadrupled, and the number of beef cattle had tripled in the period from 1870 to 1900.

Sponsored by U.S. Representative Edward T. Taylor (D-Colorado), the Taylor Grazing Act set aside approximately 80 million acres of land for “grazing districts,” valuable for forage crops.

Editorial label (1941-06-19) by Harold LeClair IckesU.S. Department of the Interior Museum

To administer these grazing districts, Secretary of the Interior Harold L. Ickes created a Division of Grazing and called upon ranchers, state officials and Department of the Interior employees to determine grazing district boundaries. The first grazing district was established in Wyoming on March 20, 1935. By June of that year, more than 65 million acres had been placed into grazing districts which are still in effect today.

The Division of Grazing was renamed the U.S. Grazing Service in 1939, and in 1946, it merged with the Department of the Interior’s General Land Office to form the current-day Bureau of Land Management.

Diorama: "Grazing on the Public Domain" (1936/1937) by National Park Service, Eastern Museum LaboratoryU.S. Department of the Interior Museum

Preliminary 1935 plans for the Interior Museum’s General Land Office exhibit alcove include a diorama niche to address the Taylor Grazing Act, but coming up with something compelling enough to “justify the use of a diorama” proves to be a challenge. In a status report submitted on June 23, 1936, field curator John Ewers writes:

“A considerable number of photographs were supplied by the Division of Grazing which might serve as a possible basis for this diorama. However, none of them, nor any group of them, appeared to offer possibilities for an interesting diorama.”

He simultaneously notes that the Division of Grazing's informational display currently on view at the 1936 Texas Centennial means “that better photographs are now obtainable.” Suitable photographs are evidently secured, because construction begins on the Grazing diorama later in the year.

While no archival images have yet been found documenting this particular diorama in progress, a 1937 report confirms that the setting of the completed diorama is one of the grazing districts established in Utah as a result of the Taylor Grazing Act.

Viewers are supposed to note the positive effects the Taylor Grazing Act is having. The range fenced in to demarcate the grazing district has good grass cover and is neither eroded nor overgrazed. The herd has access to a sizable watering hole, and . . .

. . . the sheep are sturdy and healthy.

Luncheon of the National Park Advisory Board at Ford's Theatre (1936) by Allan Rhinehart, National Park ServiceU.S. Department of the Interior Museum

Luncheon of Fall 1936

In spring 1936, Ned Burns departs Morristown for the nation’s capital to more closely oversee buildout of the new, high-profile Interior Museum and by August is named the acting chief of the Museum Division, with offices in the Department of the Interior headquarters. Burns leaves Arthur A. Jansson in charge of the EML’s interim operations and ultimate closeout from Morristown to its new home on the second and third floors of Ford’s Theatre in Washington, D.C. By autumn of 1936, the transition from New Jersey to Ford’s Theatre is complete, but some of the Morristown personnel leave rather than relocate. This photograph is from a Fall 1936 luncheon gathering of National Park Service officials and Advisory Board members in the new Ford's Theatre workspace. In conjunction with the luncheon, the Advisory Board members view exhibition materials about to be shipped to Vicksburg National Military Park, as well as several completed dioramas for the Interior Museum, including the six visible here (from left to right): "Washington and Lafayette at Morristown," "Land Office," "Coal Mine Explosion," "Geological Survey River-Measurement," "Fort Union Trading Post," and "Irrigation of a Cotton Field."

Planning and Construction Continue

All the while, work continues feverishly on both the new Department of the Interior headquarters at 18th and C Streets, N.W., and on the exhibits for the Interior Museum to open therein. Murals, relief maps, didactic materials, label text, illustrations, scientific models, and the dioramas still in progress are finalized in the Ford's Theatre space, as well as at . . .

Located along the George Washington Parkway in Virginia, near Mount Vernon, the Fort is decommissioned by the Secretary of War in 1933 and repurposed as a camp for the Civilian Conservation Corps (CCC). The camp employs hundreds building trails and clearing timber, and for a short time—between 1933 and 1938—approximately 20 enrollees work under the supervision of National Park Service (NPS) personnel on components of various NPS museum projects in eastern states.

The Museum Opens

Department of the Interior employees start occupying the newly completed headquarters building in early 1937. The museum team based at Ford's Theatre gets the go-ahead in June 1937 to begin installing the dioramas in the museum wing. All is on track for the museum to open at the end of the year, but then a contractor strike and difficulties with a manufacturer push the schedule back by three months. In March 1938—three years since the museum's planning committee first formed—the Interior Museum is finally ready to open.

Invitations are sent to internal stakeholders and also to senators, congressmen, the director of the American Association of Museums, the Secretary of the Smithsonian, the president of the National Geographic Society, the head of the Forest Service, the Department of Commerce, the Department of Agriculture, the director of the National Zoo, the directors of the National Gallery of Art and the Corcoran, and the curators at the Army Medical Museum and the American Red Cross Museum.

Several photographs like this one are also released to the press in advance of the opening. The dioramas feature prominently.

The Museum's soft opening occurs on Tuesday, March 8, 1938, at 8:00 p.m., with the public grand opening held the next morning.

On the opening weekend (March 12 and 13, 1938) there are special hours from 1 to 4:30 p.m. Highlighted in all the invitations and press materials are the “striking exhibits” showing the “manifold activities” of the Department's bureaus and offices. The publicity touts nearly 8,000 square feet showcasing 95 exhibit units, 1,000 objects, nearly 500 photographs, 250 maps and charts, 100 models, 12 large wall maps and countless text panels.

Response to the museum is overwhelmingly positive. Attendance routinely tops 10,000 a month with people coming from every state in the nation and from many foreign countries. Admission is free, and the museum remains open on Saturdays. Visitors are particularly enthralled by the dioramas, which are frequently mentioned in visitor comments.

On April 1, 1939—just over a year into the Interior Museum’s existence—oversight is transferred from the National Park Service's Museum Division to the Office of the Secretary of the Interior. Harry Raul comes on as the curator and museum administrator. In his June 30, 1939, fiscal year report he writes, “The museum is growing in influence, in its services, and also its needs. Natural changes and improvements continually should be expected. No museum should be allowed to become stagnant.”

To this end, Raul concentrates on keeping the displays fresh and up to date. In the coming years, more dioramas are added . . . .

Diorama: "Sponge Fishing, Tarpon Springs, Florida" (before September 1940) by National Park Service, Museum DivisionU.S. Department of the Interior Museum

Sponge Fishing at Tarpon Springs

While the 1935 planning abstract for the Interior Museum suggests two diorama niches for the Bureau of Reclamation's exhibit alcove, the Museum opens in 1938 with only one Reclamation diorama: "Boulder Dam (Hoover Dam)." The other diorama—in theory, showing irrigated crops in the Pacific Northwest’s Yakima Valley—is never constructed, at least not for the Interior Museum. The niche is used instead to display a large transparency of the Roosevelt Dam. In 1940, however, the Department of the Interior gains a new bureau, the U.S. Fish and Wildlife Service, as a result of a transfer and merger of the Department of Commerce’s Bureau of Fisheries and the Department of Agriculture’s Bureau of Biological Survey. An expedient way for the Interior Museum to reflect this organizational addition is to uncover the unused niche and install a related diorama. Although it remains unclear whether “Sponge Fishing” is purpose-built for the Interior Museum or simply recycled from another venue, its installation in September 1940 nevertheless highlights an interesting aspect of the new bureau.  

Sponge harvesting began in Tarpon Springs, Florida, in the late 1880s. Where sponges grew in clear, shallow waters, workers operating from boats could hook and retrieve them using long poles. But it was Greek sponge buyer John Cocoris (1877–1944) who revolutionized operations in 1905 by introducing sponge divers. He encouraged experienced Greek sponge divers from his homeland in the Dodecanese Islands to immigrate to Tarpon Springs and establish businesses. They based their Florida-built sponge boats on traditional Mediterranean sailing vessels but modified them with engines for greater maneuverability.

In 1906, the Bureau of Fisheries—a precursor of today’s U.S. Fish and Wildlife Service—was authorized to enforce sponge-taking regulations in the Gulf of Mexico and the Straits of Florida.

By the 1930s, Tarpon Springs had cultivated an internationally-important sponge industry, generating 500,000–600,000 pounds of sponges and millions of dollars a year.

The Sponge Fishing diorama is unique in that the scene is split so viewers can see what is going on underwater as well as topside.

The diorama is also partially mechanized. A small motor powers the fish to swim in circles in the reef.

A hard hat diver collects sponges from the sea floor.

The diver is equipped with a helmet, breathing hose, and leaded weights. It is a dangerous, physically demanding occupation requiring skill and precision. By the early 1940s, approximately 90% of U.S. sponge production is the result of divers, with the remaining 10% done by the traditional hooking method.

Workers aboard the sponger string the harvested sponges on deck to dry.

While natural sponges had been used for years in lithography and ceramics, demand soars during this time period. A May 17, 1943, U.S. Fish and Wildlife Service press release about Tarpon Springs states:

“Best known to the public through their household uses, sponges have long been vastly important in arts and industries and are now serving a variety of wartime purposes. Surgical operations and the cleaning of many instruments and machines of war require the absorptiveness, durability and softness found only in sponges.”

Diorama: "Alaska-Juneau Gold Mining Company Mill" (This diorama scene was duplicated for various clients from 1938 until at least 1945) by National Park Service, Museum DivisionU.S. Department of the Interior Museum

Alaska-Juneau Gold Mining Company Mill

An act of March 1, 1873 (17 Stat. 484) transfers responsibility for territorial affairs in Alaska from the Department of State to the Department of the Interior. By the early 1930s, the Interior is integrally involved with the operations of the Alaska Railroad and the Alaska Road Commission. In May 1934 President Franklin D. Roosevelt authorizes a new Division of Territories and Island Possessions within the Department of the Interior to coordinate oversight of Alaska, Hawai‛i, the Virgin Islands, and Puerto Rico. The annual reports from the Governor of Alaska to the Secretary of the Interior throughout the 1930s consistently underscore mining, fishing, and tourism and focus on the territory’s industrial, commercial and development outlooks. It is therefore no surprise when, in 1946, Interior Museum director Harry Raul reports that one of the new features in the museum’s exhibit alcove for the Division of Territories and Island Possessions is “an unusually large animated diorama showing the harbor and environs of the city of Juneau, Alaska.” The alcove was specially modified with an additional niche to accommodate the display. 

Assembling the "Alaska-Juneau Gold Mining Company Mill" diorama (1938) by National Park Service, Museum DivisionU.S. Department of the Interior Museum

It is believed that more than one copy of this diorama was made, with the initial one being completed in 1938 at a cost of $3,500.

Captured in the diorama are the mid 1930s operations of the Alaska-Juneau Gold Mining Company Mill (AJGMC) in Juneau, Alaska. The AJGMC mined low grade gold ore on the outcrop of the Juneau Gold Belt. The company's tunnels and mill site stretched to the Gastineau Channel, the waterway between the southeastern Alaska mainland and Douglas Island.

Gold shipments from Alaska in fiscal year 1938 amounted to more than $18 million.

The diorama contains a series of small motors drawing 840 watts of power. One mechanism controls the boat's bow bobbing in the water . . .

. . . another controls the mine cars running along the track, and . . .

. . . the lights in some of the structures cycle on and off as the "sun" rises and sets over a 2-minute period to simulate a day. Because the real-life AJGMC operated around the clock, 363 days per year, many of the building lights in the diorama also remain on during the nighttime sequence.

The Legacy of the Dioramas

The Interior Museum tantalizingly proclaims in its late 1930s promotional brochures that, "Here is history made vivid and unfolded before the eye. . . ." Indeed, the dioramas are among the items that leave the most enduring impressions upon generations of museum-goers.

Detail from 1939 Interior Museum brochure (1939) by U.S. Department of the Interior MuseumU.S. Department of the Interior Museum

In 1941, Ned Burns publishes his seminal National Park Service Field Manual for Museums. In codifying exhibition principles, techniques and museum best practices, Burns includes several drawn directly from his tenure with the Interior Museum.

Today, however, fewer and fewer examples remain from the 1920s–1950s heyday of dioramas in American museums. Dioramas have not always endured the test of time—materially or philosophically—and museums nationwide have often discarded their dioramas or otherwise replaced them with newer forms of display.

The Interior Museum itself underwent extensive renovations beginning in 2009 as part of building-wide structural and mechanical modernization efforts. At that time the dioramas were deinstalled to protect and preserve them. These “stories in miniatures” are still part of the museum’s collection and are powerful reminders of the themes valued by the Department of the Interior in the 1930s.
