Unsurprisingly, ranked in top place is Bill Gates with his £52.3 million fortune. Gates is a seasoned collector who has made purchases such as Leonardo da Vinci's Codex Leicester collection of writings, which he bought for a cool £19 million. Also in Gates' collection is Lost on the Grand Banks, by Winslow Homer which he bought for nearly £24 million.

Chasing Gates' tail is Mexico's Carlos Slim, who made his billions in telecom, and also founded Museo Soumaya, Mexico City. The museum has a collection in excess of 60 000 artworks, with pieces span from the 15th to the 20th century.

Moving along the list, in sixth place is David Koch, who last year donated £43 million to New York's Metropolitan Museum.

LVMH CEO Bernard Arnault opened the Fondation Louis Vuitton in Paris last year (read more here.) The building houses Arnault's extensive collection and was designed by Frank Gehry.

Former Mayor of New York City, Michael Bloomberg follows Arnault. A collector of Old Masters, Bloomberg's collection includes Joshua Reynolds and Thomas Gainsborough, as well as reportedly contemporary works by Warhol and Jasper Johns.
