Sol M. Edidin, 60, a Washington lawyer and former car leasing executive, died of cancer Monday at George Washington University Hospital.

Mr. Edidin, who lived in Clifton, Va., moved to this area and established a general law practice here about 1971.

Earlier, he was a vice president, secretary and general counsel of the Hertz Corporation in Chicago and New York City. From 1949-57, he was on the legal staff of the Tennessee Valley Authority.

Mr. Edidin was a native of Chicago and a graduate of the University of Illinois. In 1949, he earned a law degree from the University of Chicago, where he was a member of the Law Review Board.

Mr. Edidin was a member of the National Motor Vehicle Safety Advisory Council in 1964-65. He also was an instructor at the University of Tennessee Law School and a lecturer at the Practicing Law Institute.

In the 1970s, he was executive director and general counsel of the Car and Truck Renting and Leasing Association.

He served in the Army in World War II.

Survivors include his wife, Lore, of Clifton; two sons, Stephen and Peter, both of New York City; his mother, Frieda Edidin, and a brother, Theodore, both of Jacksonville, Fla., and a sister, Stella Topol of Skokie, Ill.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society.
