Jack Karnehm
Jack Karnehm (18 June 1917, Tufnell Park, north London, England – 28 July 2002, Crowthorne, Berkshire) was a British snooker commentator, who was regularly heard on BBC television from 1978 until 1994, and a former amateur world champion at the game of English billiards. Karnehm was also a professional snooker and billiards player. Besides his commentary, perhaps his major contribution to the game was his development of the swivel-lens glasses, which enabled Dennis Taylor to win the World Snooker Championship in 1985. These were spectacles which were set at a compensatory angle, so the player could look along  the shot through the optical centre of the lens. The originals had been designed by Theodore Hamblin, and pioneered by Fred Davis in 1938. Karnehm, who had served a five-year spectacle-making apprenticeship, made many pairs in his family business, but his upside-down design was a considerable improvement – it offered wider peripheral vision – and helped Taylor win the 1985 world title. Despite being best known to snooker audiences, Karnehm's passion was billiards. As a non-professional player, he was a ten-time London Amateur Billiards Champion, and also won the English Amateur Billiards Championship in 1969. That  October, he took the IBSF World Billiards Championship title. Karnehm turned professional in 1970, and was a challenger for the world title in 1971 and 1973, losing to Leslie Driffield and Rex Williams respectively. He was Chairman of the Billiards Association and Control Council when the Council nominated Leslie Driffield as the challenger to reigning champion Rex Williams for the professional Billiards Championship. Williams declined to play Driffield within the five months time limit that the BA&CC Council had set, which expired on 7 July 1970, and forfeited the title, which was then contested between Driffield and Karnehm in June  1971. On 1 October 1970, the Professional Billiard Players Association, which had been reestablished in 1968 Williams and seven other players, disaffiliated from the BA&CC. It changed its name to the World Professional Billiards and Snooker Association on 12 December 1970, and declared itself the governing body for the professional game, recognising Williams as champion. Driffield and Karnehm were, at first, the only two professionals to recognise the BA&CC's authority over the game. In 1980, Karnehm beat Williams to win the UK Billiards Championship, his only professional title. Karnehm also turned professional in snooker in 1971, his best result  coming when losing 4–5 to Chris Ross in the U.K. Championship of 1977. Karnehm is perhaps best known for his one-liner when he was commentating on a match between Cliff Thorburn and Terry Griffiths, at the Crucible in 1983. The match was famous because, during the match, Thorburn completed the first maximum at the Crucible. As Thorburn lined up to pot the black, Karnehm uttered the words: 'Good luck, mate'. Karnehm was also a noted snooker coach, and, in 1985, released an instructional video, 'Understanding Modern Snooker'. He continued to coach, and was still President of the Radstock Billiards  association until 2000. He died suddenly in 2002, aged 85, after an afternoon working on his garden in extreme heat.
