Philip Cortelyou Johnson (July 8, 1906 – January 25, 2005) was an American architect best known for his works of modern and postmodern architecture. Among his best known designs are his modernist Glass House in New Canaan, Connecticut, and postmodern 550 Madison Avenue in New York, designed for AT&T, and 190 South La Salle Street in Chicago.
In 1978, he was awarded an American Institute of Architects Gold Medal and in 1979 the first Pritzker Architecture Prize.
In 2020, in the wave of the name changes that followed the murder of George Floyd, 40 architects, designers, and educators, calling themselves the Johnson Study Group, asked that galleries named for him at the Museum of Modern Art be renamed, and other honors removed from public view. Johnson was an open fascist and anti-Semite, said Hitler was better than Roosevelt, and "welcomed" the arrival of World War II. He was also an open white supremacist, and in effect segregated the Museum's collections. Not until 2016 was a work by a Black architect or designer added to the Museum's collections. He "innovated white supremacy in architecture".
