Charles T. Lloyd, 91, a federal government lawyer who served on the assistant secretary of defense’s international affairs staff before retiring in 1979, died Nov. 30 at a hospice in Tavares, Fla., of kidney failure.

His death was confirmed by a son, Thomas B. Lloyd.

Mr. Lloyd began his federal career after graduating in 1947 from Yale Law School. He worked for the State Department and then became assistant general counsel of the General Services Administration. By the 1960s, he was working at the Defense Department and was involved in the development of the F-16 fighter jet as well as military base rights overseas, his son said.

Charles Thomas Lloyd was a native of Hartford, Conn., and a 1942 graduate of Brown University in Providence. During World War II, he served in the Army and participated in the Normandy invasion. His decorations included the Bronze Star Medal.

He moved from Potomac to Rehoboth Beach, Del., in 1980 and to Mount Dora, Fla., in 1984. He was a member of Congressional Country Club in Bethesda and a past scoutmaster for the Boy Scouts.

His first wife, Maryann Burke, died in 2003 after 57 years of marriage. In 2010, he married Dorothy H. Rae.

Besides his wife, of Mount Dora, survivors include three children from his first marriage, Bruce Lloyd of Pasadena, Calif., Thomas B. Lloyd of Eustis, Fla., and Diane L. Yaeger of Scarsdale, N.Y.; six grandchildren; and three great-grandchildren.
