Margaret Ehrlich

1915-2007

Margaret Ehrlich received her undergraduate degree in physics at the University of Vienna in 1938. From 1941-47, she was chief X-ray technician at Grady Memorial Hospital in Atlanta, Georgia. Ehrlich was hired by L.S. Taylor in the National Bureau of Standards (NBS, now the National Institute of Standards and Technology, NIST) X-Ray Section of the Atomic Physics Division in 1947. She received her Ph.D. in physics from the Catholic University of America in 1955, with a thesis on X-ray and electron interactions with photographic emulsions.
