Otto Bruno Schoenfeld (1871–1938) was an all-round sportsman, competing at fencing, wrestling and boxing. Born in 1871 in Leipzig, Germany, he came to the United States as a boy, his family originally settling in Milwaukee, Wisconsin. By the time of his death he was known as 'one of the mightiest amateur athletes of all time'. In April 1900 he made his way, unsponsored, to the Exposition Universelle (World's Fair), where he won the world fencing championship. Some months later he competed at the 1900 Summer Olympics in Paris for the United States in masters sabre.
