Gertrude Joy Grimm

Joy worked in retail and advertising, at W. & J. Sloane in New York, and at J. L. Hudson in Detroit.

During World War II, she worked in the personnel office of the War Department in Washington, D.C., then was commissioned by the Navy to work as assistant to WAVES commander Mildred McAfee. She helped to formulate housing standards for the women's reserve program, and established statistical records of the program's personnel. In 1946, she was decorated with a Navy Commendation ribbon by the Secretary of the Navy, for "outstanding performance of duty as a special assistant to the director of the Women's Reserve."
