JOHN CALVIN PORTMAN, JR., FAIA (1924-2017)

Portman was born in Walhalla SC and had five sisters. He graduated from the Georgia Tech in 1950 and gained fame when his firm completed the Merchandise Mart (later  AmericasMart) in Atlanta in 1961. The multi-block Peachtree Center was begun in 1965 and would expand to become the main center of hotel and office space.  The Hyatt Regency Atlanta, Portman's first atrium hotel, led to many more, including the Westin Bonaventure Hotel in Los Angeles, the New York Marriott Marquis, and the Renaissance Center in Detroit.  In 2009, Portman's work was featured in a major exhibition at Atlanta's High Museum of Art.  Portman married Joan (Jan) Newton. They had six children, including Jarel Portman and John Portman III.  John Portman III worked with his father for several years and took over the office after his death.   Portman III died in 2020, with 5 children, John IV and four more.
