James Jeffreys was a prominent British boxer known for his impressive career in the early 20th century. Born on April 7, 1874, he became the World Heavyweight Champion in 1899 and held the title until 1905. Jeffreys was celebrated for his strength and skill in the ring, earning the nickname "The Boilermaker" due to his background in the trade. After retiring from boxing, Jeffreys briefly returned to the sport in 1910 to face Jack Johnson, the first African American heavyweight champion. This match was highly publicized and marked a significant moment in boxing history, reflecting the racial tensions of the time. Jeffreys ultimately lost the fight, which contributed to his legacy in the sport.
