The Web site of the American Writers Museum (a proposed new museum on American literature) highlights the Time magazine covers since 1923 that have featured U.S. writers. Mystery fans will appreciate the ones with Craig Rice (1946), Mr. Moto creator John P. Marquand (1949), noted mystery critic and Columbia University provost Jacques Barzun (1956), Scott Turow (1990), and Michael Crichton (1995). Missed is James Gould Cozzens (1957), author of the Haycraft-Queen Cornerstone work The Just and the Unjust (1942).
Has a writer ever been selected as Time's Person of the Year? I can't recall.
