Charles Brush
Charles Brush was the first inventor to successfully sell lighting equipment in the United States. Brush grew up on a farm outside of Cleveland. He became interested in repairing equipment, and that interest grew to the experimental field of electricity. Like Edison, Brush read everything he could about electricity, and then began his own experiments. He wanted to study electricity in college, but there were no programs in the study of electricity, so Brush studied chemistry and mining. After graduating, he began building his first dynamo generator, which powered a single light.
Brush began installing his small systems across the U.S. and licensing utility companies and cities to use his system for electric street lights. He installed the first electric lights on Broadway in New York City and the first to illuminate Niagara Falls. His street lighting installations ranged from Albany to San Francisco.

Elihu Thomson
Albumen photograph print of inventor and electrical pioneer Elihu Thomson. Thomson's early work with dynamos, arc lamps, and alternating-current power made him one of the top inventors of the late 19th century. His Thomson-Houston company merged with the Edison General Electric Company in 1892 to form General Electric.

Investors convinced Thomson to move to Connecticut and form the American Electric Company in 1880. The business was on the verge of failure in 1883 when Charles Coffin, a shoe factory owner in Lynn, MA took an interest, moved the business to Lynn, and renamed it Thomson-Houston.

Early alternating current dynamo and exciter developed by Elihu Thomson. Thomson was among the first to research alternating current electricity. His research began in the 1870s, but he set it aside for several years due to the demand for direct current equipment.
Thomson returned to alternating current research in the 1880s, as the direct current business matured and other companies, including Westinghouse, had begun to explore alternating current. The transformer was an essential element to an AC power system.
Van Depoele was a native of Belgium who moved to the United States in 1869 at the age of 23. He began experimenting with electricity at the age of 10. His father was master mechanic for a railroad and Charles became fascinated by the telegraph. After he moved to the U.S., he worked building furniture, and continued working with electricity in his free time, building arc lamps and dynamos. While in Detroit, he created demonstrations of arc lighting, electric factory motors, and electric streetcars. He moved to Chicago, and set up a larger railway demonstration at a Chicago fair. By 1887 he had 9 street railway installations and had established a business selling both arc and incandescent lamps. In 1888 he sold his business to Thomson-Houston, and moved to Lynn, MA where he worked on developing electrical machinery for mines.
View shows the growth of Thomson-Houston from its founding in 1883 to the merger with Edison General Electric in 1892. The company expanded from a single building to an entire factory complex in less than 10 years.
James J. Wood
James Wood got his first job at the age of 11, working for a lock manufacturing company in Branford Connecticut. In 1874 Wood moved to Brooklyn New York, where he began working for the Brady Manufacturing Company. In his first year, he quickly rose to the positions of superintendent, and Chief Engineer. While working full time, Wood earned a degree in Mechanical Engineering from Brooklyn Polytechnic Institute, graduating in 1878.
In 1877 Wood witnessed a demonstration of James Fuller’s experimental dynamo, and was instantly fascinated with the concept of electricity. He studied electricity and physics in his spare time, and developed his own ideas about how to improve the electric dynamo. Wood began to think that Fuller’s dynamo had flaws - it was too noisy, used too much power, and ran too hot. Wood decided that he could develop a dynamo himself which addressed these problems.
Wood worked on his dynamo for two years, meeting with many failures but hope and the optimism of youth kept him going. In 1880 his machine was complete, and he had the joy of seeing the dynamo light an arc lamp.
Using the funds from a patent, Wood was determined to improve his design, working to improve voltage in his machine. His new dynamo eliminated the flash or “spark” where the brushes of the machine made contact with the commentator. When complete, Wood’s dynamo weighed 120 pounds, and ran with little noise. Wood went into business with Brady, and eventually James Fuller, creating the Fuller-Wood Company. They developed an arc light to accompany the dynamo, and became the first to use electricity to illuminate the Statue of Liberty.

Wood went to work for McDonald, relocating to Fort Wayne, Indiana. After McDonald’s death in 1898, the Fort Wayne Electric Company became part of GE. Wood continued to manage the Fort Wayne manufacturing plant while working on his own inventions.
James Wood was one of the first people to recognize the marketability of the household refrigerator. Under him, Fort Wayne played a major role in the manufacturing of General Electric’s refrigerator business. He was influential in the design and development of the modern electric refrigerator. He was able to see the development and large scale of success of the refrigerator before his death in 1928.
Wood and Fort Wayne became leaders in producing small motors. Pictured is a 1902 General Electric fan, produced by its subsidiary, the Fort Wayne Electric Works, and carrying the FWEW abbreviation in the center of the fan grill.
Frank Sprague
Frank Sprague was born in 1857 and was a graduate of the U.S. Naval Academy. Sprague became interested in electricity while serving in the Navy, but left in 1883 to work for Edison. Sprague oversaw some of Edison’s more challenging utility installations, and introduced mathematics methods into Edison’s design process. Sprague left Edison in 1884 to found the Sprague Electric Railway & Motor Company. Sprague introduced regenerative braking and a motor that maintained constant speed (under a varying electrical load). Sprague installed the first large scale railway system in Richmond, VA in early 1888. Sprague sold his business to Edison in 1890, and focused his efforts on electrifying the elevator. Until his death in 1934 Sprague continued to make improvements in his inventions.

In less than 15 years, the electrical industry transformed from a collection of small startup companies to a large industry dominated by two companies, GE and Westinghouse. As the industry grew in the early 1880s, Edison and Thomson-Houston became two leaders, and purchased other companies to expand product lines or strengthen their patent control. Edison purchased Sprague Electric, which developed one of the first electric streetcar systems, while Thomson-Houston bought Brush Electric to strengthen its position in power generation and arc lighting, and Van Depoele Electric for its street railway system.
William Stanley and Westinghouse
William Stanley invented the first practical transformer, making large scale alternating current installations possible. While working for George Westinghouse in 1886, Stanley created the first large scale demonstration of an alternating current transmission system in Great Barrington, MA, developing a system that transmitted electricity nearly a mile to 19 businesses on Great Barrington’s Main Street. Stanley started electrical factories in Great Barrington and Pittsfield. His Pittsfield plant was purchased by GE in 1903.

The Founding of General Electric
On April 15, 1892, General Electric was formed through a merger of the Edison General Electric Company and the Thomson-Houston company. The merger brought together two of the largest companies in the fledgling electrical industry.
The merger had been under discussion since at least February 1891, when the top staff of Thomson-Houston, based in Lynn, Massachusetts, visited Edison’s main plant in Schenectady. J.P. Morgan, Edison’s chief financial backer, and Charles Coffin, president of Thomson-Houston, explored the merger to improve profitability.
Charles Coffin became the president and chairman of the new company. Elihu Thomson became the chief inventor. Thomas Edison served for 10 years on the GE board of directors, but decided to focus on other projects, including the phonograph, motion pictures, iron mining, and cement manufacturing.

Three factors that played into the merger were the pooling of patents, commitment to alternating current, and economies of scale. It was impossible for one company to build the ideal electrical system without infringing on the patents from the other company. While Edison had control of the best consumer product, the incandescent lamp, Thomson-Houston had developed a superior generating system. Thomson had embraced the latest in generating technology, alternating-current, Edison had maintained his commitment to the older direct current system.

Curtis Turbine
Turbine engineers Charles Curtis, Oscar Junggren, William Le Roy Emmett and Henry Reist defied their detractors and accomplished the impossible when they built two 5,000 kW turbine-generator sets for Samuel Insull, the president of the Chicago Edison utility company in 1903. This is the same Insull who had worked with Thomas Edison. Insull had a vision of giant electricity-generating machines that would make electricity affordable for everyone. Both GE and Chicago Edison risked the reputations and financial stability of their companies by engaging in the project. Chicago Edison constructed a space ten times larger than was necessary in the end to house the turbine-generators.
Despite this revolutionary achievement, by 1909 the two machines were obsolete. Engineers continue to push the limits of technology by making machines larger and more powerful than once imagined.
