Born and raised in Portrush, a town that would soon be linked even more closely to The Open, Daly led by four at the halfway stage of the 1947 Championship after rounds of 73 and 70.
A 78 in round three dropped the Northern Irishman back into a four-way tie at the top, alongside Henry Cotton, Arthur Lees and Norman von Nida.
Yet it was Daly who ultimately prevailed, courtesy of a closing 72, to ensure the Claret Jug made its maiden journey across the Irish Sea.
Amateur star Frank Stranahan almost forced a play-off in dramatic fashion. He needed to hole a 9-iron at the last to tie Daly and his ball finished just a foot away from its target.
