United Nations Headquarters, New York, NY

Wallace K. Harrison was an American architect who designed major institutional and civic structures across the twentieth century, including the General Motors Building and the Metropolitan Opera House at Lincoln Center in New York. His practice encompassed modernist public buildings, corporate headquarters, and cultural institutions marked by a restrained geometric vocabulary and attention to urban scale. Harrison worked extensively in collaboration with other architects and planners, shaping postwar American urbanism through large-scale commissions.
