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.

Charles H. Warner Jr. was a New York-based architect active from the 1940s through the 1990s. Warner designed many buildings on college campuses in the United States and abroad. Additionally, Warner built many hotels, working extensively with Hilton Hotels to build new establishments all over the world. His work in foreign countries underscores his core architectural principle of designing "in context," or incorporating local culture and tradition into his buildings. Some of his more well-known hotel projects include the Ramses Hilton in Cairo and the Caribe Hilton in San Juan.
