Retired Air Force Brig. Gen. Baskin R. Lawrence Jr., 70, a bomber pilot who later worked in research and development, died Saturday at the Rutland Hospital in Rutland, Vt., following a heart attack.

A resident of Fairfax Station since 1964, Gen. Lawrence was vacationing at the time he was stricken.

A native of Seneca, S.C., Gen. Lawrence graduated from Clemson University with a degree in electrical engineering. He was commissioned in the Army reserves in 1932 and was assigned to flight training in the old Army Air Corps in 1934.

During World War II, he commanded the 91st Bomb Group in England. He later activated the 482d Pathfinder Group, the first Army Air Force unit equipped to carry out bombing with the assistance or radar.

After the war, Gen. Lawrence held a number of posts in the research and development field. He earned a master's degree in aeronautical engineering at the Air Force Institute of Technology. At the time of his retirement for reasons of health in 1964, he was chief of the Command Control Defense Systems of the Air Defense Command at Hanscom Air Force Base, Mass.

Gen. Lawrence's decorations included the Silver Star, the Legion of Merit with one Oark Leaf Cluster, the Air Metal with one Oak Leaf Cluster and the Army and Air Force Commendation Medals.

Survivors include his wife, Cheryl C., of Fairfax Station; two daughters, Shelley L. Vickery of Oakton, and Sherin L. Rose of Fairfax; three sisters, Mildred Daniel, Beryl Lowry and Mary Puckett, all of Seneca, S.C., and five grandchildren.
