David Robert Duval is born in Jacksonville, Florida, the son of club and teaching professional Bob Duval. He was US Junior Amateur Champion in 1989 and turned pro in 1993, winning twice on the Nike Tour before earning his full PGA Tour card in 1995. He won 13 times on the PGA Tour between 1997 and 2001, the last of these wins being the 2001 Open Championship at Royal Lytham & St Annes. Known as "Double D", he also won a number of other events around the world, including the 2000 WGC-World Cup, partnered with Tiger Woods. After winning the Players Championship in March 1999, his third win in under three months, he became World No. 1, displacing Tiger Woods and holding the position for 14 weeks. He held the No. 1 spot a second time, for just one week, that August.
Following his Open Championship win and a title in Japan in November 2001, Duval lost his form completely through a mixture of injuries and personal problems, and has not won since, although he surpised everyone with a tie for second in the 2009 US Open.
At the 1999 Bob Hope Chrysler Classic, Duval became only the third player in PGA Tour history to shoot 59, and the first to do so in a final round, eagling the 72nd hole to clinch victory.
Thomas Daniel (Tom) Weiskopf is born in Massillon, Ohio. At 6ft 3in (1.91m), he was one of the tallest golfers of his generation, with an elegant, fluid and hugely powerful swing which produced a high and very long ball flight.
After winning the prestigious Western Amateur in 1963 he turned pro in 1964. Success didn't come immediately, but when it did he became a prolific winner, taking 16 PGA Tour titles from 1968 to 1982, including the 1973 Open Championship at Royal Troon, in a year which saw him win seven times in all, taking him to No. 2 in Mark McCormack's (now the Official World) World Golf Ranking. He was also a four-time runner-up at the Masters, runner-up at the 1976 US Open and third in the 1975 PGA, as well as winning the 1972 Piccadilly World Match Play Championship and the 1973 World Series of Golf.
Despite these successes he was frequently branded an under-achiever, often preferring to go fishing or hunting rather playing golf. After playing on the 1973 and 1975 US Ryder Cup teams and having qualified to play again in 1977, he decided not to take part and went big-game hunting instead. He also had a famously short temper on the golf course, earning the nickname of "The Towering Inferno" for his outbursts.
He joined the Senior Tour in 1993 and won four times there, inlcuding the 1995 US Senior Open. As his playing career came to and end he went into course design and is now a world-renowned golf architect, counting Loch Lomond among his many fine courses.
