Richard Ehrlich worked at Los Alamos in the Theoretical Physics Division, during the Manhattan Project. He later worked at Oak Ridge in the 1960s.
Ehrlich married Eleanor Ewing on July 7, 1945. The wedding took place at Fuller Lodge. In 1946, the couple moved to Cornell University. Here, Ehrlich completed his Ph.D. research. From 1947 to 1975, the family lived in Schenectady, while he worked for General Electric.
Due to changes at the Knolls Atomic Power Laboratory, Richard was relocated to General Electric’s San Jose location. They would remain in California for thirteen years and eventually move to Gainesville, Florida in 1999.
