Ginzton became CEO and chairman of Varian Associates after Russell Varian died of a heart attack and Sigurd Varian died in a plane crash.[7]
Ginzton was awarded the IEEE Medal of Honor in 1969 for "his outstanding contributions in advancing the technology of high power klystrons and their application, especially to linear particle accelerators."
Ginzton was born in Ukraine[9] and lived in China before moving to California in 1929.[10]
