Sir Donald George Bradman, AC (27 August 1908 - 25 February 2001), often referred to as "The Don", was an Australian international cricketer, widely acknowledged as the greatest batsman of all time. Bradman's career Test batting average of 99.94 has been cited as the greatest achievement by any sportsman in any major sport. The story that the young Bradman practised alone with a cricket stump and a golf ball is part of Australian folklore. Bradman's meteoric rise from bush cricket to the Australian Test team took just over two years.

In 1930-31, against the first West Indian side to visit Australia, Bradman's scoring was more sedate than in England--although he did make 223 in 297 minutes in the Third Test at Brisbane and 152 in 154 minutes in the following Test at Melbourne. However, he scored quickly in a very successful sequence of innings against the South Africans in the Australian summer of 1931-32. For NSW against the tourists, he made 30, 135 and 219. In the Test matches, he scored 226 (277 minutes), 112 (155 minutes), 2 and 167 (183 minutes); his 299 not out in the Fourth Test, at Adelaide, set a new record for the highest score in a Test in Australia. Australia won nine of the ten Tests played over the two series.  At this point, Bradman had played 15 Test matches since the beginning of 1930, scoring 2,227 runs at an average of 131. He had played 18 innings, scoring 10 centuries, six of which had extended beyond 200. His overall scoring rate was 42 runs per hour, with 856 (or 38.5% of his tally) scored in boundaries. Significantly, he had not hit a six, which typified Bradman's attitude: if he hit the ball along the ground, then it could not be caught. During this phase of his career, his youth and natural fitness allowed him to adopt a "machine-like" approach to batting. The South African fast bowler Sandy Bell described bowling to him as, "heart-breaking ... with his sort of cynical grin, which rather reminds one of the Sphinx ... he never seems to perspire".  Between these two seasons, Bradman seriously contemplated playing professional cricket in England with the Lancashire League club Accrington, a move that, according to the rules of the day, would have ended his Test career. A consortium of three Sydney businesses offered an alternative. They devised a two-year contract whereby Bradman wrote for Associated Newspapers, broadcast on Radio 2UE and promoted the menswear retailing chain FJ Palmer and Son. However, the contract increased Bradman's dependence on his public profile, making it more difficult to maintain the privacy that he ardently desired.  Bradman's chaotic wedding to Jessie Menzies in April 1932 epitomised these new and unwelcome intrusions into his private life. The church "was under siege all throughout the day ... uninvited guests stood on chairs and pews to get a better view"; police erected barriers that were broken down and many of those invited could not get a seat. Just weeks later, Bradman joined a private team organised by Arthur Mailey to tour the United States and Canada. He travelled with his wife, and the couple treated the trip as a honeymoon. Playing 51 games in 75 days, Bradman scored 3,779 runs at 102.1, with 18 centuries. Although the standard of play was not high, the effects of the amount of cricket Bradman had played in the three previous years, together with the strains of his celebrity status, began to show on his return home.  Bradman joined the Royal Australian Air Force (RAAF) on 28 June 1940 and was passed fit for air crew duty. The RAAF had more recruits than it could equip and train and Bradman spent four months in Adelaide before the Governor-General of Australia, Lord Gowrie, persuaded Bradman to transfer to the army, a move that was criticised as a safer option for him. Given the rank of Lieutenant, he was posted to the Army School of Physical Training at Frankston, Victoria, to act as a divisional supervisor of physical training. The exertion of the job aggravated his chronic muscular problems, diagnosed as fibrositis. Surprisingly, in light of his batting prowess, a routine army test revealed that Bradman had poor eyesight.  Invalided out of service in June 1941, Bradman spent months recuperating, unable even to shave himself or comb his hair due to the extent of the muscular pain he suffered. He resumed stockbroking during 1942. In his biography of Bradman, Charles Williams expounded the theory that the physical problems were psychosomatic, induced by stress and possibly depression; Bradman read the book's manuscript and did not disagree. Had any cricket been played at this time, he would not have been available. Although he found some relief in 1945 when referred to the Melbourne masseur Ern Saunders, Bradman permanently lost the feeling in the thumb and index finger of his (dominant) right hand.  In June 1945, Bradman faced a financial crisis when the firm of Harry Hodgetts collapsed due to fraud and embezzlement. Bradman moved quickly to set up his own business, utilising Hodgetts' client list and his old office in Grenfell Street, Adelaide. The fallout led to a prison term for Hodgetts, and left a stigma attached to Bradman's name in the city's business community for many years.  However, the SA Cricket Association had no hesitation in appointing Bradman as their delegate to the Board of Control in place of Hodgetts. Now working alongside some of the men he had battled in the 1930s, Bradman quickly became a leading light in the administration of the game. With the resumption of international cricket, he was once more appointed a Test selector, and played a major role in planning for post-war cricket.  After his return to Australia, Bradman played in his own Testimonial match at Melbourne, scoring his 117th and last century, and receiving PS9,342 in proceeds. In the 1949 New Year Honours, he was appointed Knight Bachelor for his services to the game, becoming the only Australian cricketer ever to be knighted. He commented that he "would have preferred to remain just Mister". The following year he published a memoir, Farewell to Cricket. Bradman accepted offers from the Daily Mail to travel with, and write about, the 1953 and 1956 Australian teams in England. The Art of Cricket, his final book published in 1958, is an instructional manual.  Bradman retired from his stockbroking business in June 1954, depending on the "comfortable" income earned as a board member of 16 publicly listed companies. His highest profile affiliation was with Argo Investments Limited, where he was chairman for a number of years. Charles Williams commented that, "[b]usiness was excluded on medical grounds, [so] the only sensible alternative was a career in the administration of the game which he loved and to which he had given most of his active life".  Bradman was honoured at a number of cricket grounds, notably when his portrait was hung in the Long Room at Lord's; until Shane Warne's portrait was added in 2005, Bradman was one of just three Australians to be honoured in this way. Bradman inaugurated a "Bradman Stand" at the Sydney Cricket Ground in January 1974; the Adelaide Oval also opened a Bradman Stand in 1990, which housed new media and corporate facilities. The Oval's Bradman Stand was demolished in 2013 as the stadium underwent an extensive re-development. Later in 1974, he attended a Lord's Taverners function in London where he experienced heart problems, which forced him to limit his public appearances to select occasions only. With his wife, Bradman returned to Bowral in 1976, where the new cricket ground was named in his honour. He gave the keynote speech at the historic Centenary Test at Melbourne in 1977.  On 16 June 1979, the Australian government awarded Bradman the nation's second-highest civilian honour at that time, Companion of the Order of Australia (AC), "in recognition of service to the sport of cricket and cricket administration". In 1980, he resigned from the ACB, to lead a more secluded life. Answer this question using a quote from the following article:
