A world number one professional squash player, Jansher Khan was born on 15 June 1969, in Peshawar. During his career he won the World Open a record eight times and the British Open six times. Jansher's skill of movement singled him out from the competition. Jansher Khan's retirement brought an end to nearly 50 years of domination by Pakistan in the sport of squash.
Jansher won the World Junior Squash Championship title in 1986. At the time, the men's professional squash was dominated by another great Pakistani player, Jahangir Khan. Jahangir won the pair's first few encounters in late-1986 and early-1987. Jansher then scored his first win over Jahangir in September 1987, beating him in straight games in the semi-finals of the Hong Kong Open.
Jansher then went on to beat Jahangir in their next ten consecutive encounters. This included a win in the semi-finals of the 1987 World Open, following which Jansher claimed his first World Open title by beating Australia's Chris Dittmar in the final.
Jansher officially announced his retirement from squash in 2001. He won a total of 99 professional titles and was ranked the World No. 1 for over 10 years.
In August 2007, Jansher announced that he was coming out of retirement to play in a Professional Squash Association tournament in London in October 2007. He said in a news conference that the reason for his comeback was that, I feel, I am mentally and physically fit to play the international circuit for another three to four years. He lost in the opening round of the event to England's Scott Handley.
