Gordon Bunshaft (1909-1990) was an American architect who, as a partner at Skidmore, Owings & Merrill, had a significant impact on large-scale corporate architecture. His projects include such significant urban office towers as the Lever House in midtown Manhattan, as well as modern office campuses set in natural landscapes, including such examples as the American Can Company in Greenwich, Connecticut or the Connecticut General Life Insurance Company headquarters in Bloomfield, Connecticut. Additionally, his interest in art caused him to actively integrate work by well-known modern artists into the public plazas and interiors of SOM's projects. The professional aspects of this collection can be found in clippings, project photography, oral history records, and publications, however, the majority of the collection is personal and reflects the life of Gordon and his wife Nina Bunshaft. Through correspondence, snapshots, objects, and personal papers the collection focuses on the Bunshafts' friends, their travels, and their impressive art collection of both modern and ancient sculptures and paintings.
