John H. ("Jack") Richards, a professor of organic chemistry and biochemistry at Caltech whose research was focused on gaining a molecular understanding of the mechanisms of protein function, passed away on Thursday, April 23, 2015. He was 85 years old.
Thomas Anthony Tombrello, Caltech's Robert H. Goddard Professor of Physics, passed away on September 23, 2014, at age 78. His studies of nuclear reactions in the 1960s helped show how chemical elements are created.
Gerry Neugebauer, Caltech's Robert Andrews Millikan Professor of Physics, Emeritus, passed away on September 26, 2014, of complications from spinocerebellar ataxia, a neurodegenerative disease. He was 82.
Frank Earl Marble (Eng '47, PhD '48), Caltech's Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering and Professor of Jet Propulsion, Emeritus, was one of the fathers of modern jet engines.
Frederick Burtis Thompson, professor of applied philosophy and computer science, emeritus, passed away on May 27, 2014. The research that Thompson began in the 1960s helped pave the way for today's "expert systems" such as IBM's supercomputer Jeopardy! champ Watson and the interactive databases used in the medical profession. His work provided quick and easy access to the information stored in such systems by teaching the computer to understand human language, rather than forcing the casual user to learn a programming language.
