Raphael
Raphael was enormously productive, running an unusually large workshop and, despite his death at 37, leaving a large body of work. Many of his works are found in the Vatican Palace, where the frescoed Raphael Rooms were the central, and the largest, work of his career. The best known work is "The School of Athens" in the Vatican Stanza della Segnatura. After his early years in Rome much of his work was executed by his workshop from his drawings, with considerable loss of quality. He was extremely influential in his lifetime, though outside Rome his work was mostly known from his collaborative printmaking.
Philip Johnson
It was one thing to build a glass cathedral in California, and another to build a corporate headquarters skyscraper in the center of Manhattan, the showcase of modern architecture. Shortly after the Crystal Cathedral, working in collaboration with John Burgee, he completed one of his most recognizable buildings, the AT&T building (later named the Sony Building, and now 550 Madison Avenue). Built between 1978 and 1982, a skyscraper with an eight-story high arched entry and a split pediment at the top which resembled an enormous piece of 18th-century Chippendale furniture. It was not the first work of Postmodern architecture—Robert Venturi and Frank Gehry had already built smaller scale postmodern buildings, and Michael Graves had completed the Portland Building in Portland Oregon (1980–82) two years before the AT&T Building; and most of the building was in a traditional modernist style; but because of its Manhattan location and size it became the most famous example of postmodern architecture.
