Gregory John Norman (born 10 February 1955) is an Australian professional golfer and entrepreneur who spent 331 weeks as the world's number one ranked golfer in the 1980s and 1990s. He is nicknamed, The Great White Shark or sometimes simply The Shark — a reference to Norman's blond hair, size and aggressive golf style and the shark inhabiting Australian waters.

Greg Norman was one of the most accomplished golfers of the 1980s and 1990s, a golfer with great achievements but who also gained a reputation for falling short of expectations. That's only because expectations for Norman soared so high early in his career. Growing up in Australia, Norman's games were rugby and Australian Rules football. He didn't spend much time at golf until age 15 in 1970. He caddied for his mother during her weekly round, and borrowed her clubs following the round.

Two years later Norman was playing at scratch. He trained as an Australian PGA professional, and played amateur events around his home country.

In 1976, Norman turned pro. He joined the European Tour in 1977 and that year earned his first victory. In 1982 he was that tour's leading money winner. The following year, he joined the U.S. PGA Tour.

Norman first came to worldwide prominence when he narrowly missed catching Jack Nicklaus at the 1986 Masters. He pushed his approach shot to the 72nd green into the stands, the first of what would be numerous narrow defeats, unlucky breaks and unfortunate collapses.

Bob Tway holed a bunker shot at the 1986 PGA to snatch the win away from Norman; Larry Mize holed a long chip shot in a playoff at the 1987 Masters to deny Norman again. Perhaps most famously, Norman blew a 6-shot lead entering the final round to lose the 1996 Masters to Nick Faldo by 5 strokes.

But amid the bad breaks were plenty of wins - 20 of them on the U.S. Tour. Norman won 3 U.S. money titles and 3 U.S. scoring titles. He was Player of the Year in 1995 and for one stretch in the early '90s held the No. 1 world ranking for 331 weeks.

And there were British Open titles in 1986 and 1993.

In 2008, at the age of 53, Norman made an unlikely run at a third British Open title, holding the third round lead before finishing tied for third.

Also in 2008 - just a couple weeks before his British Open run - Norman married tennis legend Chris Evert.

Off the course, Norman was a highly successful businessman, building Great White Shark Enterprises into an empire that included course design, apparel, development and production companies, merchandising and licensing.
