Daniel David Fiszman (9 January 1945 – 13 April 2011) was an English diamond dealer, best known as a shareholder in and director of Arsenal Football Club, and played a leading role in the club's move from Highbury to Ashburton Grove, now known as Emirates Stadium.

Fiszman was born in Willesden, North London and was the son of a Belgian Jewish couple who fled the Nazis during World War II.^{[citation needed]}

Fiszman made his fortune in diamonds, building Star Diamonds Group which traded in rough diamonds.^[1] Star Diamonds Group also owns 16% of Abbeycrest, whose major clients include Argos and Asda. He sold the group in 2007 for £150M, to concentrate on his role in completing Arsenal's new stadium.^[2]

Other shareholdings took his total worth to around £236m, ranking him 348th on the 2008 Sunday Times Rich List^[3] (351st in 2007, 273rd in 2006, 305th in 2005 and 207th in 2004).

Fiszman bought into Arsenal Football Club and became a board member through his purchase of an 8% stake from his friend David Dein, starting with 10,000 shares in 1991.

In March 2007 Fiszman sold a block of 659 shares for over £3.9m to Stan Kroenke Sports Enterprises (KSE).^[4] This was a significant sale as reducing his stake to less than 25% resulted in a loss of veto rights over any future changes to the company statutes. Speculation linked this with a move abroad where he would substantially reduce any Capital Gains Tax liability that would come with a sale of his stake in the club.^[5] Fiszman stated his desire not sell any more of his shares for the foreseeable future,^[6] after the sale of 5,000 ordinary shares to Kroenke takes the American's stake in Arsenal Holdings plc to 12,756 Shares (representing 20.5%). On 27 March 2009 Fiszman sold 5,000 ordinary shares of £1 each in Arsenal Holdings plc to KSE, UK, Inc, at a price of £8,500 per share.^[7] On 11 April 2011, two days before his death, he sold his Arsenal shares amounting to 16.11% of club's stake to KSE, due to his declining health.^[8]

Fiszman and his wife Sally lived in St Prex near Geneva, Switzerland. His hobbies included running and flying – he was a fully qualified commercial jet pilot. Fiszman had been undergoing treatment for throat cancer at the time of his death. He died on 13 April 2011 aged 66.^[9]
