Early life
Dalton Pritchard earned a BSEE degree in Electronics from Mississippi State University in 1943. He received specialized radar training at Harvard University and MIT when he entered the U.S. Army Signal Corps, then served as captain in the Asiatic-Pacific Theater during World War II. He was awarded the Bronze Star Medal.[1]
RCA career
In 1946, Pritchard joined RCA Laboratories as a Member of the Technical Staff at Riverhead, NY, where he was engaged in communications research. In 1950 he transferred to RCA laboratories, Princeton, NJ. There his research involved many aspects of color television systems development: receivers, color kinescopes, transmitting encoders, cameras, and magnetic recording of TV. This work included the planning and testing of systems and circuits proposed for adoption by the National Television System Committee (NTSC).
Between 1960 and 1970, Pritchard worked on video processing circuitry for color TV receivers, colorimetry and decoder matrix methods, information display techniques, and analog techniques employing charge-coupled devices for TV applications. He also worked on Selectavision VideoDisc development. As a member of the Television Research Laboratory, he was involved in research related to high-definition TV (HDTV) systems that included applications of digital signal processing techniques.[2]
Awards
Pritchard received seven RCA Laboratories Outstanding Achievement Awards. He is a Fellow of the IEEE and of SID and member of Sigma Xi, Tau Beta Pi, and Kappa Mu Epsilon. He is listed in American Men and Women of Science and in Who's Who in the East.
