Correction: An earlier version of this obituary incorrectly reported Mrs. Efron’s name at birth. Her name was Hope Bachrach Newman, not Hope Newman Bachrach.

Hope N. Efron, who worked as an economist at the Department of Labor’s Bureau of Labor Statistics from 1939 to 1942, died June 16 at Sibley Memorial Hospital. She was 94.

The cause of death was congestive heart disease and pneumonia, said her son Marc Efron.

Hope Bachrach Newman was born in New York and was a 1939 economics graduate of Hunter College in New York.

She was featured in the 2005 documentary “Government Girls of World War II,” a locally produced film featuring stories from women who flocked to Washington in the 1940s to assist with the World War II effort.

She received special commendations for her volunteer work with the American Councils for International Education and Youth for Understanding, both international student-exchange programs. She also volunteered at Georgetown Day School and was a member of Temple Sinai, both in Washington.

Her husband of 55 years, Samuel Efron, died in 1997.

Survivors include two children, Marc Efron of Chevy Chase and Eric Efron of Helotes, Tex.; and twin grandsons.
