For almost 50 years, Gubby Allen was the key influencer behind English cricket – captain, chairman of selectors and MCC strategist – yet he remained an elusive behind-the-scenes figure. Born in Australia in 1902 and educated at Eton, he became the protégé of Sir Pelham ‘Plum’ Warner. His refusal to bowl Bodyline on the 1932/33 tour set him at odds with Douglas Jardine but helped propel him to the captaincy of the 1936/37 Ashes, when he was pushed to breaking point. After distinguished wartime service, Allen became one of cricket’s most influential administrators. As chairman of selectors from 1955 to 1961 he oversaw a golden era and worked with Don Bradman to stamp out throwing. But his attachment to amateur ideals and his central role in the 1968 D’Oliveira Affair tarnished his reputation. Drawing on a treasure trove of new material, including Allen’s private correspondence, Mark Peel uncovers a driven, complex figure whose influence shaped the game for decades.
