Robert Allan Jacobs (1905-1993) was an American architect and designer active in the United States from the 1930s until his retirement in the early 1980s. His work consists primarily of commercial projects, including numerous skyscrapers in New York City, along with a richly varied corpus of other institutional, residential, and commercial projects--primarily centered in New York City and its surrounding suburbs but ranging as far afield as South Africa and the Dominican Republic. The son of the notable Beaux-Arts architect Harry Allan Jacobs, Robert Allan Jacobs was educated at Amherst College and the Columbia University School of Architecture. Jacobs began his career as a disciple of Le Corbusier, went on to serve as a designer and draftsman for Harrison & Fouilhoux, and then formed a partnership with Ely Jacques Kahn in 1941--thus commencing three decades of pioneering collaborative design work that would leave an indelible mark on the Manhattan skyline. Together, Kahn & Jacobs made their debut with the Municipal Asphalt Plant in 1941 and went on to design such iconic projects as 100 Park Avenue (1944), the Universal Pictures Building (1947), 1407 Broadway (1950), 425 Park Avenue (1957), the Seagram Building (in collaboration with Mies van der Rohe and Philip Johnson, 1958), the Astor Plaza Building (in collaboration with Carson & Lundin, 1961), the New York Telephone Building (1969), and One Astor Place (1970).
