A veteran of World War I, he won the 1927 US Open, 1930 PGA Championship, and the 1931 British Open. His 1930 campaign was overshadowed by Bobby Jones' Grand Slam, and Armour seems to have been overlooked. His book How to Play Your Best Golf All the Time became a best-seller and for many years was the biggest-selling book ever authored on golf.
Following his passing in 1968, Tommy Armour was interred in the Ferncliff Cemetery in Hartsdale, New York.
