Cooper has been described as "a public-school educated product of the English establishment". He was born in British India, the son of Bransby Henry Cooper and his wife Mary. His father was an officer in the East India Company and died in 1857, his mother returning to England to live at Hemel Hempstead. Cooper was educated at Rugby School where he played cricket in the school XI between 1860 and 1862 where he was coached by Alfred Diver.
Cricket
Cooper played club cricket for Southgate Cricket Club and Free Foresters before going on to play first-class cricket for Middlesex and Kent. He made his first-class debut in 1863 for a Middlesex side against Surrey before the county club was formally founded and played in the first match Middlesex played after their formation in 1864. He also played for MCC and the Gentlemen amateur side, often playing with WG Grace who made his Gentlemen debut in the same match as Cooper. He played eight times for Middlesex sides between 1863 and 1867 before moving to Tunbridge Wells and playing nine times for Kent in 1868 and 1869. After the 1869 season Cooper moved firstly to the United States, where he played cricket for St George's Cricket Club at Hudson City in 1870, and then to Australia in 1871. He played for Victoria in 11 matches, including nine intercolonial matches against New South Wales. He has been described as being "recognised as the leading batsman in colonial cricket." In the inaugural Test match at Melbourne in 1877 Cooper was expected to be named as captain as Victorians outnumbered New South Welshmen. Dave Gregory was instead elected by the players for this honour. In what was to be his only Test match Cooper scored 15 and 3 runs and took 2 catches whilst becoming the first player to make their Test debut on their birthday. In all first-class matches, Cooper scored 1,600 runs at a batting average of 20.51, took 41 catches and made 20 stumpings. His only first-class century was a score of 101 made in 1869 for the Gentlemen of the South against the Players of the South. His partnership of 283 runs with WG Grace at The Oval in 1869 set a record for an opening partnership in first-class cricket which stood until 1892. His Wisden obituary said that he batted in a "very attractive style" with "patience and sound defence" and that he was a "fairly good wicketkeeper without approaching the front rank".
Professional and later life
Cooper worked on the London Stock Exchange. He was in business in both the United States and Australia, eventually becoming a senior official in the Customs Department at Queenscliff and Melbourne. After marrying Helen Wilkinson in 1875 Cooper played less cricket. The couple had three daughters. He died at Geelong in 1914 aged 70 and is buried in the Geelong Eastern Cemetery.
