Never heard of this guy but it's a great story:
Dan Jansen was an American speed skater in the late '80s and early '90s. Just before his first event in the 1988 games, Jansen's sister Jane lost her battle with Leukemia. He promised to win the gold for her, but after getting off to great starts in each race, he fell. This photo was taken after one of those races. But six years later (the Winter Olympic cycles changed after the 1992 games) Dan did win the gold and took a victory lap with his young daughter, Jane.-buzzfeed
