Sir Donald George Bradman was an Australian cricketer widely acknowledged as the greatest batsman of all time with a career Test batting average of 99.94. During a 20-year playing career, 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, 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 was knighted in 1949, being the only Australian cricketer ever to receive a knighthood and the first Test cricketer so honoured.
