Private equity baron Short helped John Grayken build Lone Star into a €60bn investment machine, with some audacious deals in Asia in the 1990s.
He then struck out on his own. The dealmaker (55) set up Kitano Partners and later Kildare partners to buy stuff as Europe's economy began to recover. Kildare raised €2bn from investors and spent it rapidly, loading up on commercial, leisure and industrial real estate assets across Ireland and Europe.
He purchased the Foyleside and Forestside shopping centres in the North as well as €100m worth of loans associated with developer Michael O'Flynn's business. Recently, he started to flip some of these properties to profit on the recovery, selling Le Méridien Parkhotel in Frankfurt and Le Méridien hotel in Munich.
Short picked up an Irish passport in 1999, and bought Sunderland football club from a group of Irish investors in 2008, and, despite his huge wealth, looks powerless to prevent the club from being relegated this year.
Short also bought Skibo Castle, the former home of billionaire industrialist Andrew Carnegie, which he now runs as an exclusive private-members club. The castle hosted the wedding of Madonna and Guy Ritchie. He also owns a €40m beachside pad in Hawaii.
