Byron Nelson won $2,000 from a total purse of $10,000 in 1944 when this event was called the Texas Open. Sam Snead won in 1945, and Ben Hogan won it the next year in 1946.
This week, 156 players are vying for the $1.242 million check that goes to the winner from the total purse of $6.9 million.
Byron Nelson's name was added to the tournament in 1968, and it has raised over $121 million for local charities since its inception.
Tom Watson, a Nelson protege, is the only four-time winner, but Snead won on three different occasions, and Jack Nicklaus and Bruce Lietzke both won here twice.
