Sylvia C. Winkelman, 75, a retired vice president and buyer for the old Erlebachers women's fashion stores in Washington, died Aug. 31 at her home in Washington after a heart attack.

Mrs. Winkelman was born in Philadelphia and graduated from the University of Pennsylvania. She moved to Washington in 1937, the year she and her husband, Jules, brought the Erlebachers store on F Street NW. They later added a store on Connecticut Avenue.

Erlebachers was one of the stylish stores in the city and Mrs. Winkelman contributed to its success in this regard. She was among the first to notice that French women often wear boots in good weather as well as bad. She is credited with having started a trend by selling boots for all occasions at her stores.

The Winkelmans operated their business until 1970, when they sold the Connecticut Avenue shop. The F Street store was closed earlier.

Mrs. Winkelman was a member of the advisory board of the Women's National Bank, the board of the Women's Committee of George Washington University Hospital and the board of the Washington Theatre Club.

In addition to her husband, of Washington, survivors include two children, Steven A., and Ann Brown, and a sister, Alma Eanet, all of Washington, and six grandchildren.
