Laurence A. Stone, 98, a retired Army lieutenant colonel who was a longtime ordnance officer before becoming a specialist in military procurement matters, died March 31 at a retirement facility in Napa, Calif.

He had congestive heart failure, a grandson, Richard Rosenberg, said.

Lt. Col. Stone served in the Army from 1939 to 1965 and was an ordnance officer during World War II. After the war, he spent more than three years with U.S. occupation forces in Germany, leading a unit that rebuilt military vehicles.

In the early 1960s, Lt. Col. Stone was part of a group that consolidated several technical service and supply branches of the Army into the Army Materiel Command.

After his military retirement, Lt. Col. Stone spent 28 years as a civilian employee of the Army Materiel Command and helped develop the earned value management system of evaluating and managing military procurement projects.

From 1993 to 1999, he worked for Comprehensive Technologies International in Northern Virginia and later was a consultant to Engineering Management Concepts until he was well into his 80s.

Laurence Asher Stone was born in Boston and was a 1935 graduate of the Massachusetts Institute of Technology. He attended the Army’s Command and General Staff College in the 1950s.

He was a longtime Arlington County resident and was a member of the Fort Belvoir Jewish congregation. He moved to Napa in 2003.

His wife of 45 years, Lillian Franklin Stone, died in 1980.

Survivors include his companion since 1996, Janet Altman of Napa; two daughters from his marriage, Marjorie Rosenberg of Potomac Falls and Nancy Rubin of Ponte Vedra Beach, Fla.; five grandchildren; and four great-grandchildren.
