Harrison's work in the mid-20th century comprised large, modernist public projects and office buildings. He worked for
McKim, Mead & White and
Bertram Grovesnor Goodhue from 1916 to 1923, and later formed a series of architectural partnerships. Harrison participated with the architectural teams involved in the
construction of Rockefeller Center in New York City, completed in 1939. His brother-in-law was married to
John D. Rockefeller Jr.'s daughter, Abigail and Harrison served as a designer and architectural adviser for
Nelson Rockefeller, notably in the years when Rockefeller was governor of New York. In 1941, Harrison joined with
Max Abramowitz to form the firm of
Harrison & Abramowitz. In partnership with Abramovitz, Harrison designed scores of university and corporate buildings, as well as churches: including: The First Presbyterian Church (
”The Fish Church”), Stamford, Connecticut, (1958), the
Time & Life (1959) and
Socony-Mobil (1956), both designated New York City landmarks. Among Harrison's most noted projects are the
Metropolitan Opera House at the
Lincoln Center for the Performing Arts and the
Empire State Plaza in
Albany, New York. He also served as Director of Planning on the
United Nations complex, which was built on slaughter house property contributed by the Rockefeller family (the Rockefellers owned the Tudor City Apartments across First Avenue). Harrision developed the design for the
Pershing Memorial in
Washington, D.C., which is now home to the National World War I Memorial. In addition to his architectural work, Harrison served as master planner and supervising architect for a number of important
Long Island-based projects, including the
World's Fairs of 1939 and
1964 in
Flushing, Queens, and
LaGuardia and
Idlewild (now
John F. Kennedy) airports. Harrison collected works by Calder and Léger and commissioned new ones for buildings that he designed, including his country house in
West Hills, New York on Long Island, a pavilion at the
1939 New York World's Fair, parts of Rockefeller Center; and the United Nations headquarters. Léger waited out part of
World War II by painting a mural at the bottom of Harrison's swimming pool. Léger also created a large mural for the home's circular living room and sculpted an abstract form to serve as a skylight. Calder's first show is said to have taken place at the home. In 1965, Harrison was appointed to a commission to choose modern art works for the
Governor Nelson A. Rockefeller Empire State Plaza Art Collection in Albany, NY. Between 1941 and 1943, Harrison designed and built the Clinton Hill Coops, a 12-building coop complex split between two campuses along Clinton Ave. in
Brooklyn, to house the Brooklyn Navy Yards workers. Harrison's architectural drawings and archives are held by the Drawings and Archives Department of
Avery Architectural and Fine Arts Library at
Columbia University. Harrison was a member of the
United States Commission of Fine Arts from 1955 to 1959. In 1967, Harrison received the
AIA Gold Medal. In 1938, he was elected into the
National Academy of Design as an Associate member, and became a full Academician in 1948. ==Personal life==
