Michael Grenfell "Mike" Davies (9 January 1936 – 2 November 2015) was a Welsh professional tennis player, entrepreneur and administrator. He had a 60-year career in the tennis business, first as an amateur and professional tennis player, including a period as the number one ranked player in Great Britain and a member of the British Davis Cup team, then as an entrepreneur and one of the pioneers of the professional game. Playing career Davies was born in Swansea, Wales. He took up tennis at the age of 11, and was discovered by Fred Perry and Dan Maskell. He played on the British Davis Cup team with Bobby Wilson, Billy Knight and Roger Becker. In 1952 Davies went to Australia for the first of three winter visits to work with Harry Hopman, the Australian Davis Cup Coach, and Australian players like Lew Hoad, Ken Rosewall, Roy Emerson, Fred Stolle. It was there that Davies developed his game. From 1958 to 1960 Davies was ranked number 1 in Great Britain. He played on the Davis Cup team for Great Britain from 1956 to 1960 and had a 15/8 match record. In 1960 he reached the final of the Men's Doubles at Wimbledon with Bobby Wilson; the last time a British male reached the final of Wimbledon's Men's Singles or Men's Doubles until 2012. After that doubles final, in 1960, he was invited to turn professional with Jack Kramer for a two-year guarantee of £4,500-a-year. He joined a select group of players considered to be the best in the world such as Pancho Gonzales, Tony Trabert, Lew Hoad, Ken Rosewall and Pancho Segura. Since international tennis at this time was an amateur sport, Davies' professional status put him at odds with the ruling tennis body, the International Tennis Federation (ITF), and his membership of the All-England Club at Wimbledon was cancelled, and he became ineligible to ever play Davis Cup or any of the Grand Slams again. As well as playing he was elected to the board of the first Players' Association that was formed by this select group of approximately 12–15 players and found himself leading the charge to promote professional tennis and to fight for open tennis. Soon Davies found himself doubling up as the tour's spokesman and selling the upcoming events and taking the first steps towards a flourishing career in the promotion of tennis as a business.
