Who ran the first four minute mile?

On May 6, 1954, the Englishman Roger Bannister ran the first sub-four-minute mile in recorded history at 3 minutes 59.4 seconds. Six weeks later, John Landy, an Australian, followed suit with 3:58, breaking Bannister's record. In November, 2005, Forbes magazine declared after interviewing a number of sports experts that Bannister's four minute mile was "the greatest athletic achievement" of all time.
