John Sholto Douglas, 9th Marquess of Queensberry, was a Scottish nobleman born on February 20, 1844. He is best known for his role in the development of modern boxing rules, known as the Queensberry Rules, which were established in 1867. These rules introduced the use of gloves and standardized the length of rounds, significantly shaping the sport. Douglas was also notable for his involvement in the high-profile trial of Oscar Wilde, a famous playwright and poet. The trial stemmed from Wilde's relationship with Douglas's son, Lord Alfred Douglas, leading to Wilde's conviction for "gross indecency" in 1895. Douglas passed away on February 8, 1900.
