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.

Volume 18 is the master index for the entire collection with an alphabetical listing of aircraft covered in the first six volumes and the subject listing for items covered in the remaining 11 volumes.
The first six volumes of the Collection contain photographs and articles with three-view drawings of domestic and foreign aircraft, alphabetized by manufacturer or national origin.

Biographical / Historical:
Herbert L. Stephenson collected aeronautical memorabilia from 1925 through 1968. He compiled the materials in this collection.
At the time of processing, no attempt was made to photocopy the large number of news clippings or insert interleaving paper into the scrapbooks. Due to the fragile nature of these scrapbooks, photocopying is not recommended.
In Volume 18, the researcher will find a reference entitled "Books and Pamphlets." These books were part of the collection at the time of donation; but when the Collection was processed, these items were not found with the 18 scrapbooks. It is believed that they were transferred to the National Air and Space Museum Branch of the Smithsonian Libraries, or to the NASM Archives Aircraft Technical Manuals Collection.
