Richard Kenneth Gunn (16 February 1871 – 23 June 1961) was a British boxer, and is the oldest man to win an Olympic boxing crown ever. He achieved this feat at the age of 37 years and 254 days.
He was born in Charing Cross, London and died in Lambeth, London.
Gunn took up boxing at the Surrey Commercial Docks Boxing Club in 1893 after joining his father's East End tailoring business. He won the 1894, 1895 and 1896 Amateur Boxing Association British featherweight title, when boxing out of the various clubs.
He was so much better than his rivals at the time that authorities asked him to retire after he won his third ABA title. Gunn did so, but in 1908, having served on the ABA council for more than ten years, he returned to win the Olympic title before hanging up his gloves for good. Gunn died in London aged 90, having only lost one fight in fifteen years.
