Correction: An earlier version of this obituary incorrectly reported where Chief Master Sgt. Curtis held his final active-duty military assignment. It was at Offutt Air Force Base in Nebraska, not at Langley Air Force Base, Va. Also, his daughter Pamela A. Curtis resides in Cambridge, Mass., not in Oakland, Calif.

Richard M. Curtis, who retired from the Air Force in 1970 as a chief master sergeant and became executive officer of the U.S.-Saudi Arabia joint economic commission, died July 16 at a hospital in Melbourne, Fla. He was 86.

The cause was congestive heart failure, said his wife, Molly Tasker.

Chief Master Sgt. Curtis served in the Navy from 1943 to 1952, attaining the rank of petty officer first class. During World War II, he served as a Navy radioman during the Battle of Iwo Jima.

Starting in 1952, he spent 18 years in the Air Force and became a specialist in procurement and contracting. His final active-duty assignment was at Offutt Air Force Base in Nebraska.

As a civilian in the 1970s, he was a procurement official with the Department of the Air Force. Starting in 1979, he joined the Defense Department, where he helped write federal acquisition regulations, his family said.

He retired in 1987 from the U.S.-Saudi Arabia joint economic commission and subsequently did consulting work for the State Department in Europe, Africa and the Middle East.

He moved to Melbourne from Washington in 1998.
