Samuel Edgar Langford was a Black Canadian boxing standout of the early part of the 20th century. Called the "Greatest Fighter Nobody Knows", by ESPN, Langford is considered by many boxing historians to be one of the greatest fighters of all time. Originally from Weymouth Falls, a small community in Nova Scotia, he was known as "the Boston Bonecrusher", "the Boston Terror", and his most famous nickname, "the Boston Tar Baby". Langford stood 5 ft 6+1⁄2 in (1.69 m) and weighed 185 lb (84 kg) in his prime. He fought from lightweight to heavyweight and defeated many world champions and legends of the time in each weight class. Considered a devastating puncher even at heavyweight, Langford was rated No. 2 by The Ring on their list of "100 greatest punchers of all time". One boxing historian described Langford as "experienced as a heavyweight James Toney with the punching power of Mike Tyson".

Joe Gans was an American professional boxer. Gans was rated the greatest lightweight boxer of all-time by boxing historian and Ring Magazine founder, Nat Fleischer. Known as the "Old Master", he became the first African-American world boxing champion of the 20th century, reigning continuously as world lightweight champion from 1902 to 1908, defending the title 15 times versus 13 boxers. He was inducted into the International Boxing Hall of Fame in 1990.
