Joseph Kaplan (1902-1991) came from Hungary to the United States at a young age, studied physics at the Johns Hopkins University, established the Institute of Geophysics at the University of California at Los Angeles, became a Member of National Academy of Sciences, and led pioneering studies of the physics and chemistry of the stratosphere. Among his many honors were membership in the National Academy of Sciences, a Sigma Xi lecture, and the Hodgkin Medal of the Smithsonian Institution (1965).
