Jane S. Lehmann, 86, a Washington resident since 1966 who had been a Red Cross volunteer for 42 years in the course of her life, died at George Washington University Hospital Thursday following a heart attack.

Mrs. Lehmann was born in Grantfork, Ill., and educated at Belmont College, Nashville, Tenn., the University of Wisconsin, from which she graduated, and Syracuse University, where she did graduate work. She lived for many years in Syracuse, where her husband, Dr. William C. Lehmann, was a professor of sociology, and then in Cambridge, Mass., before moving to Washington.

Her Red Cross work began in World War I, when she was one of the first of the "Gray Ladies." Over the years she worked with emotionelly disturbed persons, in soup kitchens, and in various blood banks. She was a volunteer in the blood bank of the C.C. chapter of the Red Cross.

Mrs. Lehmann willled her body to the George Washington University Medical School for research purposes and her eyes to the Eye Bank.

In addition to her husband, of the home in Washington, survivors include a son, Dr. William L. Lehmann, of Albuquerque, N.M.; a daughter, Dr. Shirley Spohr, of Washington, and seven grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the American Red Cross, or to the American Heart Association.
