Sir Donald George Bradman, often referred to as "The Don", was an Australiancricketer, widely acknowledged as the greatest Test batsman of all time. Bradman's career Test batting average of 99.94 is often cited as statistically the greatest achievement by any sportsman in any major sport. During a 20-year playing career, Don Bradman consistently scored at a level that made him, in the words of former Australia captain Bill Woodfull, "worth three batsmen to Australia". A controversial set of tactics, known as Bodyline, was specifically devised by the England team to curb his scoring. As a captain and administrator, Dol Bradman was committed to attacking, entertaining cricket; he drew spectators in record numbers. Following an enforced hiatus due to the Second World War, he made a dramatic comeback, captaining an Australian team known as "The Invincibles" on a record-breaking unbeaten tour of England. Bradman retained a pre-eminent position in the game by acting as an administrator, selector and writer for three decades following his retirement. Even after he became reclusive in his declining years his opinion was highly sought, and his status as a national icon was still recognised—more than 50 years after his retirement as a Test player, in 2001. On the centenary of his birth, 27 August 2008, the Royal Australian Mint issued a $5 commemorative gold coin with Bradman's image and on 19 November 2009, he was inducted into the ICC Cricket Hall of Fame.
