Thomas Wade Landry (September 11, 1924 – February 12, 2000) was an American professional football coach, player, and World War II bomber pilot. Regarded as one of the greatest head coaches of all time, he was the first head coach of the Dallas Cowboys in the National Football League (NFL), a position he held for 29 seasons. During his coaching career, he created many new formations and methods, such as the now default 4–3 defense that is used by a majority of teams in the NFL, and the "flex defense" system made famous by the "Doomsday Defense" squads he built during his tenure with the Cowboys. His 29 consecutive years from 1960 to 1988 as the coach of one team is an NFL record, along with his 20 consecutive winning seasons, which is considered to be his most impressive professional accomplishment.
In addition to his record 20 consecutive winning seasons from 1966 to 1985, Landry won two Super Bowl titles in Super Bowl VI and XII, five NFC titles, and 13 divisional titles. He compiled a 270–178–6 record, the fifth-most wins all-time for an NFL coach, and his 20 career playoff victories are the third-most of any coach in NFL history.
