Louis Pisapia, 77, a retired food broker and a resident of the Washington area for more than 60 years, died Tuesday at Holy Cross Hospital in Silver Spring. He had cancer.

Mr. Pisapia was born in New York City. He moved to Washington in 1918 and began a career in the grocery business. He worked first for a meat dealer and later was manager of an A & P supermarket. In 1934, he opened the Wayside Market, a Silver Spring farmer's market, and operated it until about 1942.

He then went to work for Safeway and was a manager of meat departments in various Safeway stores in the Washington area. In 1947, he and two brothers opened the Indian Spring Market in Silver Spring, an independent food store.

Three years later, Mr. Pisapia left the store and started Parkway Aluminum Products, a home improvement firm he operated from his home in Silver Spring. He remained in that business until 1965.

He then went to work for the Jack Carpel Co., a food brokerage, and later for Kenny, Morgan & O'Reilly, another brokerage, from which he retired in 1971.

Mr. Pisapia was a member of the St. John the Evangelist Church in Silver Spring.

Survivors include his wife, Margaret, of Silver Spring; a daughter, Elizabeth (Betty) Patschak, also of Silver Spring; two sisters, Emily Shipman and Virginia Errett, both of St. Petersburg, Fla.; three brothers, Edward, of Hyattsville, Silvio, of Fort Lauderdale, Fla., and Humbert, of Silver Spring, and three grandchildren.
