740 Park Avenue ca. 1945

740 Park Avenue combined the efforts of Architect Rosario Candela, who most likely focused on apartment planning, and Arthur Loomis Harmon, who probably styled its sleek exterior. (In a similar streamline moderne style, Harmon's firm, Shreve, Lamb & Harmon, designed the Empire State Building, which was under construction when 740 Park was completed.) Setting back above the 12th floor on the building's Park Avenue side, 740 featured a distinctive two-story base of corrugated stone, a body decorated with shallow pilasters, and stainless-steel doorways with elaborate geometric decoration. The building originally contained 30 apartments and its first tenants included builder James T. Lee, whose house had stood on the site. Lee's granddaugher, Jacqueline Bouvier--later Kennedy Onassis--spent part of her childhood in the building, and, in 1937 John D. Rockefeller Jr. created a triplex apartment for his family.
