Percy Alfred Williams, OC (May 19, 1908 - November 29, 1982) was a Canadian athlete, winner of the 100 m and 200 m races at the 1928 Summer Olympics. Born in Vancouver, British Columbia, Williams surprised many - himself the most - when he won the Canadian trials and was sent out to the 1928 Olympics in Amsterdam at age 20. To his surprise, he found out that he could easily advance to the final of the 100 m event. Wikipedia
