Milton Fischer, 89, an architect who helped shape the Washington suburbs before and after World War II and later contributed to the designs of two of the toniest addresses in Washington, the Watergate and Foxhall, died Oct. 2 at Suburban Hospital in Bethesda of a cerebral hemorrhage.

By the late 1930s, Mr. Fischer was an official at the U.S. Housing Authority and handled housing plans to accommodate an influx of war-industry workers. Among the projects he administered was a housing development for blacks near the Sparrow Point Shipyard in Baltimore.

After returning from Navy service in the Pacific during World War II, Mr. Fischer resettled in Washington and oversaw the housing boom as a regional director of the National Housing Agency.

By the early 1950s, he was at a private architectural firm, and he was an associate architect on the Watergate project the following decade.

As the principal architect on the Foxhall housing complex in the early 1970s, he continued to mix residential with commercial fixtures by placing office space in the building and designing an adjacent shopping mall.

Among the other local structures he designed were the headquarters for B'nai B'rith International, the national headquarters for the American Association of University Women, the Federal Bar Building, the Georgetown Inn and St. Francis Episcopal Church in Potomac.

Born in New York, Mr. Fischer grew up in Port Chester, N.Y., and received a master's degree in architecture and planning from the University of Michigan in 1933.

A year before graduation, he received a planning fellowship from the Earhart Foundation in Ann Arbor, Mich. He also studied under Henry Wright, a renowned designer of suburban prototypes.

Mr. Fischer spent a few years in the 1930s working as a labor organizer for an architects union before coming to Washington in 1939 to join the federal housing agencies.

In the early 1950s, he joined Corning and Moore, an architectural firm in the District. The business later became Corning, Moore, Elmore and Fischer, and it was Fischer and Elmore by the time he retired in 1975.

During the last 25 years, Mr. Fischer enjoyed painting watercolors and exhibited his works at the Rehoboth Art League in Delaware and Miami Water Color Society in Florida.

Mr. Fischer, a resident of Rockville for the last two years, lived in the Washington area since the late 1930s.

He is survived by his wife of 62 years, Sophie K. Fischer of Rockville; a son, John Fischer of Fairfax; a daughter, Carol Markey of Bethesda; two grandchildren; and a sister.
