Horton was born in St Helens, Merseyside during World War 2 in 1941 and came to Jersey at the end of the Occupation in 1945 and was brought up and educated in the island. He played on the European Tour for many years from 1964 with moderate success, winning four titles and finishing fifth on the Order of Merit in 1976 and tenth in both 1974 and 1978. He was more successful as a senior player. The European Seniors Tour was founded shortly after he reached its minimum age of fifty, and he was the dominant player in its early seasons, topping the money list in 1993, 1996, 1997, 1998 and 1999. He was top of the tour's career money list for many years.
He played in the 1975 and 1977 Ryder Cups, was Captain of the PGA in 1978 and was a long serving member of the European Tour Committee.
Tommy Horton started a young professional's golf school in 1978, coaching Ian Woosnam, who went on to be a highly successful professional and eventually a Jersey resident. He stepped down as club professional at Royal Jersey Golf Club in 1999 after 25 years service to concentrate on his tournament career.
In 2000 Horton was awarded the MBE in the New Years Honours List for his services to golf, and then went on to win the opening event of the season in Barbados which was notable because the £12,500 prize money took him through £1 million career earning barrier on the European and the European Seniors Tour.
He shares the record for the lowest round in Seniors Tour history, a 62 (-10) during the final round of the 1997 Scottish Seniors Open at Newmachar.
He won seven European Tour Titles and has become the most prolific collector of titles on the European Seniors Tour, winning 23 times in his nine years.
He died at the age of 76 in 2017
