Milton Turner, 65, who worked in behalf of cultural and charitable organizations in Washington and managed his family's real estate holdings, died of cancer Wednesday at his home in Bethesda.

Mr. Turner was a benefactor of the Kennedy Center for the Performing Arts and the Smithsonian Institution, where he was a member of the Smithson Society. He was a member of the men's club at Children's Hospital, where he also had participated in fund-raising.

He and his wife, the former Lillian Scheffres, donated a collection of watercolors by Ferdinand Petrie to the Smithsonian Institution and a Petrie drawing of the late Charles Evans Hughes, a chief justice of the United States, to the Supreme Court Historical Society.

Mr. Turner was a native of Philadelphia and moved to the Washington area in 1939. He lived in Washington and Silver Spring before moving to Bethesda about 10 years ago. He served in the Navy during World War II. He later managed family real estate investments.

He was a member of B'nai Israel Congregation in Rockville. He also was a member of the Samuel Gompers Masonic Lodge in Washington and the American Federation of Mineralogical Societies.

In addition to his wife, whom he married in 1940, of Bethesda, Mr. Turner's survivors include a son, Dr. Stephen R. Turner of Durham, N.C.
