Marvin B. Ruffin, chairman of Allied Research Corp., a Severna Park-based defense contractor, died Nov. 16 at Johns Hopkins Hospital after a long illness. He was 72.
A memorial service for Mr. Ruffin, who was a resident of Severna Park, will be held at 1:30 p.m. Dec. 11 in St. Andrew's Chapel at the U.S. Naval Academy, Annapolis.
Mr. Ruffin was hired as chairman in 1971 to aid a firm then called Allied Research Associates, which was riddled with financial and administrative problems.
Spearheading the conglomerate's operation, Mr. Ruffin revived ARA and its subsidiaries, MECAR, S.A., a Belgian weapons manufacturer, and Barnes & Reinecke Inc. of Elk Grove, Ill.
Under his leadership, MECAR developed the first bullet trap rifle grenade, now in use in some 35 countries. His team also pioneered new long-range artillery rounds and tungsten dart ammunition.
Mr. Ruffin had previously worked as an engineer for airplane manufacturers and as a consultant for defense contractors worldwide.
The native of Tarboro, N.C., attended the University of North Carolina and graduated from the Naval Academy in 1941.
He later served briefly on a destroyer in the Atlantic and in Europe.
Mr. Ruffin's wife, the former Arlene F. Anderson, died in 1982.
He is survived by a daughter, Mary Ruffin of Severna Park; and four sons, Michael Ruffin of Charlotte, N.C.; Mark Ruffin of Kuala Lumpur, Malaysia; James Ruffin of Woodbridge, Va.; and William Ruffin of Severna Park.
The family suggests memorial donations to the American Cancer Society or the American Heart Association.
