Dr. Mahmoud Mourad, 57, a George Washington University medical professor, died Sunday in a car accident in Greenburgh, N.Y.

He was killed when the car he was driving and another auto collided on Rte. 9A in Greenburgh, according to a spokesman for the town police.

Dr. Mourad's wife, Maria, was the only passenger. She was listed in satisfactory condition in St. Joseph's Hospital in Stamford, Conn. The driver of the second car was treated and released.

Dr. Mourad, a specialist in rehabilitation medicine, had been on the faculty of George Washington University's medical school and director of physical medicine at George Washington University Hospital since 1970.

He also was resident training director of the George Washington University Medical Center's Rehabilitation Research and Training Center, the only facility in the metropolitan area that trains physical therapists.

A native of Egypt, he earned a medical degree at the University of Cairo in 1952. He earned a master's degree in education at New York University in 1960.

He worked as medical director of rehabilitation centers and agrarian reform clinics in Egypt before coming to this country.

Before joining the staff of the GWU medical center, Dr. Mourad spent three years as physical medicine and rehabilitation director and professor at Georgetown University's medical school.

He taught medicine at the State University of New York at Buffalo and worked on the staff of several hospitals there before moving to Washington in the mid-1960s.

Dr. Mourad was a member of the Islamic Center in Washington.

Survivors include his wife, of the home in Washington.

Friends suggest that expressions of sympathy be in the form of contributions to the Islamic Center in Washington, or to the Mahmoud Mourad Memorial Fund at the George Washington University Medical Center.
