Shirlie F. Baker, 66, a composer of popular music and a professional jingle writer who operated a Silver Spring antique shop for several years, died of cancer Wednesday at Sibley Memorial Hospital.

From the late 1940s to the early 1960s. Mrs. Baker wrote music and lyrics for annual musical productions sponsored by local organization as B'nai B'rith, Hadassah of Greater Washington, the Hexagon Club and the State Department musical troupe the Flying Follies.

She also wrote jingles for local radio announcers for several years.

She was a number of the American Society of Composers. Authors and Publishers and Broadcast Music Inc. in New York City.

Mrs. Baker lived in Bethesda and operated an antique shop in Silver Spring from the late 1960s until becoming ill about six years ago.

She was born in Albany, N.Y. and moved to Washington in the early 1940s when her husband, Philip M. Baker, a communications lawyer, went to work for the Federal Communications Commission.

She was a member of the Indian Spring Country Club in Silver Spring.

Besides her husband, survivors include a son, Robert L., of Bethesda; a daughter, Nina Feinberg of Chicago; a brother, Edward Friedlander of Chevy Chase, and three grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Montgomery County Chapter of the American Cancer Society.
