Clarence Napier Bruce, 3rd Baron Aberdare, GBE (2 August 1885 – 4 October 1957), styled The Honourable from 1895 to 1929, was a British military officer, cricketer, tennis player, and also an excellent golfer. He was the second son of Henry Bruce, 2nd Baron Aberdare. Bruce received his education at Twyford School, Winchester College and at New College, Oxford, and was admitted as a barrister of the Inner Temple; however, when World War I broke out, he decided to enter the British Army. His elder brother was killed in action in 1914, making him heir apparent to his father's barony.
