Fred Swartz at ACM 1979 [1]

Fred Swartz,
an American computer scientist and former computer chess programmer. In the early 70s, at RCA Systems Programming division in Cinnaminson, NJ, Fred Swartz started chess programming along with Victor Berman to develop the chess program CHAOS. The take over of RCA by Sperry Univac eventually moved everything to Blue Bell, Pennsylvania, until CHAOS was affiliated with the Computing Center of the University of Michigan, Ann Arbor, and its team grew in the meantime when Mike Alexander, Ira Ruben, William Toikka, Joe Winograd and later Mark Hersey and Jack O’Keefe joined by and by [2][3]. CHAOS was one of the strongest programs of the 70s and early 80s, using an unique, knowledge based and selective best-first, iterative widening approach, keeping the search tree in memory [4].

Fred Swartz in Computer vs. computer: Duel at the chessboard on ACM 1979: [7]:

Last year, the U.S. Army flew several programmers of heavyweight computer chess to the White Sands Missile Range near Alamogordo, N.M., Swartz said. He never learned the purpose of the mission, though. "I guess they wanted to find out how to use the techniques," he said. "They just asked us questions but didn't tell us what their problems are. Who knows what they do there, anyway? Guards went with us everywhere - even to the restroom. We never heard anything else afterward."
