Lawrence Award (1970) and the US Particle Accelerator School Prize (1988). He is a fellow of the APS, The AAAS and the New York Academy of Sciences. He is a member of the National Academy of Sciences. He has been active in human rights matters, being one of the co-founders of the Sakharov, Orlov, and Shcharansky (SOS) society, and was the first recipient of the APS Nicholson Medal for Humanitarian Service (1994). Dr. Sessler has served as a member of numerous committees, councils and panels. Currently, he is the President-Elect of the American Physical Society.
