John Calvin Portman Jr. (December 4, 1924 – December 29, 2017) was an American neofuturistic architect and real estate developer widely known for popularizing hotels and office buildings with multi-storied interior atria. Portman also had a particularly large impact on the cityscape of his hometown of Atlanta, with the Peachtree Center complex serving as downtown's business and tourism anchor from the 1970s onward. The Peachtree Center area includes Portman-designed Hyatt, Westin, and Marriott hotels. Portman's plans typically dealt with primitives in the forms of symmetrical squares and circles.

John Portman in the context of Renaissance Center
The Renaissance Center, commonly known as the RenCen, is a complex of seven connected skyscrapers in downtown Detroit, Michigan, United States. Located on the Detroit International Riverfront, the RenCen is owned and used by General Motors as its world headquarters. The complex includes a 73-story Marriott hotel at its center, surrounded by four 39-story office towers, connected by a large square podium containing public spaces, a conference center, retail stores, restaurants, and a company showroom.
Developed as an urban renewal project in the 1970s, the Renaissance Center was envisioned as a "city-within-a-city," and was meant to anchor a wider redevelopment of the then-declining city of Detroit. The project was developed and funded by a consortium led by the Ford Motor Company, and John Portman served as its principal architect. The five original towers were built in the Modern architectural style and completed in 1977, with two matching towers added later in 1981.
