Charles Adam Platt (1861-1933) was an American architect and landscape designer. Although best remembered today for his landscape and country house designs, he was also nationally known for his etchings, landscape paintings, commercial architecture, and institutional projects. He was largely self-taught in each of these disciplines, building his success on his ability to reconceive the classical tradition in architecture for the needs and desires of his wealthy, powerful clients. This collection contains materials related to Platt's personal and professional lives, the bulk originating from Platt's office in the form of project drawings, photographs, and records documenting architectural projects from 1901-1933.
The Julian Clarence Levi collection documents the life and activities of a twentieth century American architect and philanthropist. The collection consists of watercolor study drawings developed while Levi was a student at Columbia University and the École des Beaux Arts; architectural drawings, photographs and records for architectural projects designed and developed in association with his partner Alfred S. Taylor from 1907 until 1962; professional papers from various committees and societies Levi was associated with; personal papers and photographs, including documentation on his family and office, his academic and professional recognitions, public events, travels and social gatherings as a former Columbia alumnus; and various prints and photographs of buildings and European artists collected by Levi throughout his life.
