and the lasting legacy of these American inventors of the past and present.
Patent No. 4,472,728
While working at NASA, George Alcorn invented the X-ray imaging spectrometer. These types of imaging devices have made discoveries such as black holes and neutron stars and have greatly expanded our view of the universe.
The most powerful space telescope ever built, Chandra, uses technology based on Alcorn's original work.
George Alcorn enjoys supporting others in the pursuit of their dreams. In 1984, he won a NASA award for his work recruiting minority and women scientists and engineers.
Today, he inspires the next generation at Camp Invention®, a program of the National Inventors Hall of Fame. Alcorn proves to students that inventing and learning are not work; they are an adventure!
"If you have a good, interesting project, going to work is not coming to work. It's coming to an adventure. And I'd much rather have an adventure..."
- George Alcorn

Charles Drew supervised the collection of 14,500 pints of plasma during World War II, which were put to immediate and effective use. Banked plasma is still saving lives. Ten thousand pints are needed every day in the United States.
"The foremost lifesaver, is plasma...(it) saved shock and bleeding, and without that many men would have died before they could have reached medical care."
- Maj. Gen. Norman T. Kirk, Surgeon General of the Army
Charles Drew's legacy lives on in the many schools named for him around the country. The Charles R. Drew University of Medicine and Science (CDU) of South Los Angeles is committed to improving the lives of those in underserved communities. This is done through biomedical research and training a diverse group of future health care leaders.

Jim West enjoyed 40 years of doing work he loved at Bell Laboratories, where he earned more than 60 U.S. patents. He invented the electret microphone with Gerhard Sessler in 1962.
It is still the most common type used today, found in everything from phones and laptops to hearing aids.
Jim West is an active advocate for science education, particularly for minority students. He is an invaluable part of the programs of the National Inventors Hall of Fame, and serves on the board of The Ingenuity Project of Baltimore City Public Schools.
