About Alvin Kraenzlein
Alvin Christian "Al" Kraenzlein (December 12, 1876 – January 6, 1928) was an American track-and-field athlete known as "the father of the modern hurdling technique". He was the first sportsman in the history of the Olympic games to win four individual gold medals in a single discipline at the 1900 Summer Olympics in Paris. As of 2016, Alvin Kraenzlein is the only track-and-field athlete who has won four individual titles at one Olympics. Kraenzlein is also known for developing a pioneering technique of straight-leg hurdling, which allowed him to set two world hurdle records. In 1895, during the Wisconsin Interscholastic Championships, he won first places in the 100-yard dash, 120-yard high hurdles, 220-yard low hurdles, high jump, and shot put.
