Arthur Gilligan [SEP] Introduction
Arthur Edward Robert Gilligan (23 December 1894 – 5 September 1976) was an English first-class cricketer who captained the England cricket team nine times in 1924 and 1925, winning four Test matches, losing four and drawing one. In first-class cricket, he played as an amateur, mainly for Cambridge University and Sussex, and captained the latter team between 1922 and 1929. A fast bowler and hard-hitting lower order batsman, Gilligan completed the double in 1923 and was one of "Wisden's" Cricketers of the Year for 1924. When his playing career ended, he held several important positions in cricket, including that of England selector and president of the Marylebone Cricket Club (MCC).
