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.
