The obituary in Saturday's editions of The Washington Post about Dr. Herbert Jehle, 75, a professor emeritus of physics at George Washington University who died Jan. 14, failed to include the cause of his death. He died of a heart attack.

Herbert Jehle, 75, a professor emeritus of physics at George Washington University who was active in peace organizations, died Jan. 14 at a hospital in Koblenz, Germany. A resident of Charlottesville, he was doing research at the University of Munich.

Dr. Jehle taught theoretical physics at GW for 13 years before retiring in 1972. Since then, he had been a fellow at the University of Maryland. From 1972 to 1977, he was a consultant to the National Cancer Institute. He also had taught at several universities in Europe.

He was a member of the Charlottesville and Florida Avenue meetings of the Society of Friends. He was active in the American Friends Service Committee, the Fellowship of Reconciliation and SANE.

Dr. Jehle was born in Germany. He earned an undergraduate degree at the Stuttgart technical college and a doctorate in electrical engineering at the Berlin technical college. He escaped to this country from Vichy France in 1941.

He taught at Harvard, the Institute for Advanced Study at Princeton, the California Institute of Technology and the University of Nebraska before moving here.

Survivors include his wife, Dietlinde von Kuenssberg Jehle, of Charlottesville, and two sons, Eberhard v.K., also of Charlottesville, and Dietrich v.K., of Pittsburgh.
