Disney's film took artistic license, portraying the win as having been by a single stroke when, in reality, Ouimet won by five strokes.
Over the decade that folÂlowed his astonishing victory, the number of American golfÂers tripled.
In 2002, Mark Frost wrote a biographical account of Ouimet's U.
Open success is credited for bringing golf into the American sporting mainstream.
Frost interviewed more than 100 subjects for his book.
Ouimet thought he would have a birdie putt to win, but his approach shot checked up short of the green and his chip was only fair, leaving him with a 4-footer for a par to tie.
