Time magazine's two founders, Briton Hadden and Henry Luce, died on February 27 and February 28 respectively, Hadden in 1929, Luce in 1967.
Hadden had celebrated his 31st birthday a little over a week before his death, the exact cause of which remains a mystery but seems to have involved some sort of infection.
Hadden's short life has been the subject of two biographies: a 1949 one by his cousin, the writer Noel F. Busch, and 2006's "The Man Time Forgot," by Isaiah Wilner.
Henry Luce, meanwhile, lived on to create Fortune, Life, and Sports Illustrated, among other magazines. He was 68 at his death. Luce is the subject of numerous biographies, among them, 2010's "The Publisher: Henry Luce and His American Century," by Alan Brinkley.
