Context: Brigadier James Edward Fryer "Jeff" Linton DSO (7 May 1909–27 December 1989) was a Welsh cricketer and British Army officer.  He served with the Royal Artillery during World War II after previously playing first-class cricket for Glamorgan County Cricket Club in the 1932 English cricket season as a right-handed batsman and right-arm medium-fast bowler.  He also represented the Egypt national cricket team. Major General Alfred Henry Musson, CB, CBE, (14 August 1900–6 August 1995) was an English cricketer and British Army officer.  A right-handed batsman and right-arm medium pace bowler, he played a first-class cricket match for the British Army cricket team against Cambridge University during the 1925 English cricket season.  Between 1928 and 1931, he played three matches for Hong Kong against Shanghai. Playfair Cricket Annual is a compact annual about cricket that is published in the United Kingdom each April, just before the English cricket season is due to begin.  It has been published every year since 1948.  Its main purposes are to review the previous English season and to provide detailed career records and potted biographies of current players.  It is produced in a "pocket-sized" format, being approximately 5×4 in (i.e., about 13×10 cm), so that it is a convenient size for carrying to cricket matches.  The front cover of each edition has featured a photograph of a prominent current cricketer.  There is a popular myth that this "honour" has a "hex" or "curse" associated with it, as the player featured then invariably has a poor season. George Herbert Hirst (7 September 1871 – 10 May 1954) was a professional English cricketer who played first-class cricket for Yorkshire County Cricket Club between 1891 and 1921, with a further appearance in 1929.  He played in 24 Test matches for England between 1897 and 1909, touring Australia twice.  One of the best all-rounders of his time, Hirst was a left arm medium-fast bowler and right-handed batsman.  He completed the double of 1,000 runs and 100 wickets in an English cricket season 14 times, the second most of any cricketer after his contemporary and team-mate Wilfred Rhodes.  One of the "Wisden" Cricketers of the Year for 1901, Hirst scored 36,356 runs and took 2,742 wickets in first-class cricket.  In Tests, he made 790 runs and captured 59 wickets. Captain Joshua David Gerald Chaytor (13 May 1903 – 4 March 1937) was an Irish-born cricketer.  A right-handed batsman and right-arm fast-medium bowler, he played first-class cricket in the 1924 English cricket season and also represented the Egypt national cricket team. The 1948 English cricket season marked the final appearance in England of Don Bradman, who was shortly to retire.  Bradman's team, which included Arthur Morris, a very young Neil Harvey, Ray Lindwall and Keith Miller, went through the tour without being beaten and became known to cricket's folklore as "The Invincibles".  It was the 39th test series between the two sides which Australia won 4-0. International cricket played in the 2006 cricket season is defined as matches scheduled between May and August 2006 in all cricketing countries, as well as all international matches scheduled for the 2006 English cricket season.  Matches between January and April are defined as belonging to the 2005–06 season, while matches between September and December are defined as the 2006–07 season.  The main matches in this period were played in England, as this was in the middle of the English cricket season, but the third edition of the ICC Intercontinental Cup is defined as a part of the 2006 season, even though the tournament will stretch into February 2007, and three A teams are also scheduled to tour the northwestern part of Australia in June and July 2006. Patrick Anthony Hector, born at Islington, London on 29 July 1958, played first-class cricket in three matches for Essex in the 1977 English cricket season.
