Born in Cambridge City, Indiana in 1862, William Barefoot gained prominence in the sport as the breeder and owner of Single G. Having become successful in the poultry business, Barefoot purchased a mare named Little Gyp with plans to race her. But she soon turned lame and became a broodmare instead. On April 4, 1910 she foaled a colt with a nearly perfect letter "G" outlined in white on his forehead. Single G became a world champion, later considered to be the greatest pacer of the first half of the 20th century. William Barefoot died in 1954 in Muncie, Indiana.
