Robert Lew Robinson, 61, a retired official of the Department of Housing and Urban Development who was active in civic affairs in the Foxhall Village section of Washington, was killed Monday when he fell from an old trolley trestle in Glover Archbold Park.

Dr. James L. Luke, the D.C. medical examiner, said Mr. Robinson died of multiple injuries sustained in the fall. The accident occurred in the Foundry Branch Valley of the park near Canal Road.

Mr. Robinson had served several terms as president of the Foxhall Community Citizens Association and had been active in the preservation of the park. He opposed the building of the Three Sisters Bridge, plans for which have since been abandoned. The bridge would have connected Arlington and the District and would have taken park land in the area where Mr. Robinson died.

He also opposed plans by Georgetown University to build a heating plant along the edge of the park and other projects that would have changed its character.

Mr. Robinson was born in Wauseon, Ohio, and grew up in Toledo. He was a graduate of Ohio Wesleyan University. He was a Navy officer in World War II and commanded a landing ship in the Pacific.

He moved to Washington about 1947 and shortly thereafter joined the CIA. He subsequently worked for the Department of the Air Force and the General Services Administration. In the early 1960s, he went to work for the Federal Housing Administration, now part of HUD. At the time of his retirement, he was a management analyst.

Mr. Robinson was a member of the Metropolitan United Methodist Church and of its administrative board.

Survivors include his wife, Nancy, of Washington; three children, Robert B., of Mullan, Idaho, Katherine L. Morrison of Alexandria, and William W., of Clearlake, Wash., and one sister, Betty Beauchamp of Toledo, Ohio.

The family suggests that expressions of sympathy be in the form of contributions to Children's Hospital c/o the Treasurer, Bridge Marathon, 5601 Newington Rd. NW, Washington, D.C., 20016, or to the Ohio Wesleyan University Alumni Fund, Delaware, Ohio, 43015.
