Harry Siegstein, later known as Harry Stone, was born on March 4, 1889. By 1913, Stone made his way to Australia, where he fought and trained. From 1914 to 1916, Stone fought primarily in America and England. During this time, Stone also held the world championship welterweight title.
Overall, Stone had an extensive career. He fought over 500 bouts and cultivated a 200 bout streak of never losing by knockout -- a feat shared only by Benny Valger. He passed away in 1950.
