Vera Schafer, 91, a retired civilian analyst with the Air Force Department, died Thursday at Nothern Virginia Doctors Hospital after a stroke.

She started work with the Army Air Forces here shortly after the outbreak of World War II, continued in the same job with the Air Force Department, when it was established in 1947, and retired in 1958.

Earlier, Miss Schafer had had an extensive career with the YWCA, which began during the Mexican border clash when she was sent to San Antonio, Tex., to establish the first YWCA Hostess House.

Shortly after this country entered World War I, she was sent to the Army camp in Plattsburgh, N.Y., where she rented a large circus tent and turned it into a second Hostess House to take care of the many families who wanted to visit their sons on weekends.

The YWCA then sent Miss Schafer to France to set up residences for women telephone operators who were running the communications net for the Army Signal Corps there. She established 13 such centers in France and Germany and provided quarters for a hundred telephone operators in Paris for the Peace Conference.

Miss Schafer left the YWCA after the war to operate a chemical company housing project in Rahway, N.J. She later returned to the YWCA to help in the planning and operating of the Christadora settlement house in New York. She was manager of the YWCA Pioneer Hotel in Boston for 15 years before coming here during World War II.

Miss Schafer had lived in Falls Church since 1958.

She is survived by a sister, Clara Hoffman, of Chagrin Falls, Ohio.

The family suggests that expressions of sympathy be in the form of contributions to the John Calvin Presbyterian Church in Annandale.
