Michael, J. Grad, 71, president of Fidelity Storage Corp. in Franconia for the past 10 years, died Tuesday at the Fairfax Nursing Center in Fairfax after a heart attack.

He came to Washington in 1933 and opened the old Cornell Laundry on 14th Street NW. He later was a partner in Capital Laundry and Dry Cleaners during the late 1950s and early 1960s, then owned and operated New Deal Liquors at 7th and P streets NW. He lost the liquor store in the 1968 riots.

Mr. Grad joined Fidelity Storage a year later as the company's president.

He had belonged to the Progress and Amity clubs in Washington. He was a 32nd degree Mason, a member of Samuel Gompers Lodge, Almas Temple, and the Scottish Rite.

Mr. Grad was born in Manchester, England, and came to this country at an early age. His father died while Mr. Grad was a child, and his mother was unable to support him.

Mr. Grad spent his fifth through 13th years in foster homes in the Philadelphia area. He worked his way through high school, and was advertising manager of a chain of stores in Philadelphia by the time he was 21 years old. He owned and operated a laundry business there before coming to this area.

He is survived by his wife, Sarah, of the home in Vienna; a son, Howard, of Great Falls, Va., and four grandchildren.
