Samuel Leon Parzow, 71, a retired restaurateur in Washington who had owned the old Redskins Lounge and later the New York Lounge, died Wednesday at the Veterans Administration Hospital after a heart attack. He lived in Washington.

Mr. Parzow, who was born in Russia, came to this country as a child with his family and they settled in Atlanta City, N.J. He worked for a liquor store there. He moved to Washington after World War II service in the Army.

He operated the Eagle Bar and Grill and was part owner of the Hickory House before taking over the Redskins Lounge in about 1954. Two years later, he became owner of the New York Lounge, which he kept until the restaurant was sold in 1975.

Mr. Parzow was a member of the Progress Club, the American Legion, the Disabled American Veterans, the Veterans of Foreign Wars and the Jewish War Veterans. He was a life-member of the Zena Greenberg Chapter of Deborah, a hospital in Brownsville, N.J., which specializes in heart disease.

He is survived by his wife of 46 years, the former Rose Bell, and a daughter, Roberta H. Tavenner both of Washington; a son, David M., of Silver Spring; three brothers, Isadore, of Margate, Fla., Nathan, of Bethesda, and Morris, of Silver Spring; a sister, Eleanore Adelman of Silver Spring, and five grandchildren.
