This collection contains original (Betcam SP), master (Betacam SP), reference (1/2" VHS) videos and photographs documenting Spencer Crew, Secretary I. Michael Heyman, Arthur Molella and Jerome Lemelson in honor of the establishment of the Lemelson Center and the first Innovative Lives Program (a series of lecture-demonstrations by American inventors and entrepreneurs for young people--by Hildreth "Hal" Walker. Hal Walker discusses his background and how he became an inventor. With John Travis, a chemist from the National Institute of Standards and Technology, Walker demonstrates the properties and applications of lasers, including measuring the distance to the moon and voice communications. Walker developed laser equipment that projected images of the moon back to the earth during the 1969 Apollo moon walk.
Collection is arranged into four series. Series 1: Original videos Series 2: Master videos Series 3: Reference videos Series 4: Photographs
Biographical / Historical:
Hal Walker was born in 1933 in Louisiana. In 1951, he joined the Navy and served for four years as a qualified electrician's mate. In 1955, Walker joined Douglas Aircraft Company installing radar systems and at the same time began taking classes at L.A. City College. Soon after joining Douglas Aircraft, a series of layoffs occurred and Walker joined RCA working with the Ballistic Missile Early Warning System (BMEWS). He continued to sharpen his technical and managerial skills developing industrial and medical uses for lasers, plasma, quantum physics, and holography. By 1981, Walker joined Hughes Aircraft, the organization that brought Laser Target Designator Systems (LTDs) to the United States Army's weapons inventory. Walker retired from Hughes Aircraft in 1989 and with his wife, Dr. Bettye Davis Walker, founded A-MAN, the African American Male Achievers Network, Inc. Science Discovery Learning Center. A-MAN's mission is to utilize Science, Technology, Engineering and Mathematics (STEM)-related projects as a motivational tool and advance the educational achievement, and the intellectual and career development of African-American, Latino and other minority students pre-K thru 12thgrades.
Created by the Jerome and Dorothy Lemelson Center for the Study of Invention and Innovation in 1995.
