During the 1900 Paris Olympics, golf first appeared at the Olympic Games, and one of the last for over a century. (The sport returned to the Olympics for the 2016 Rio Games.)
The first American woman, Margaret Abbott to win an Olympic gold medal was not aware of what she won. Records suggest she went her entire life oblivious to her historic achievement. Her mother, Mary Ives Abbott entered the competition as well. It was the first and only time in Olympic history that a mother and daughter competed in the same sport, in the same event, at the same time. Margaret Abbott passed away during 1955 unaware of the milestone she had set.
