Alexander Turnbull

New Zealand librarian

Alexander Horsburgh Turnbull (14 September 1868 – 28 June 1918) was a New Zealand merchant, dandy and book collector.On his death, his collection became the nucleus of the Alexander Turnbull Collection, initially housed in his residence, Turnbull House, but as of 1987 housed with the collections of the National Library of New Zealand, a body formed in 1965 by the amalgamation of three libraries, including the one bearing Turnbull's name.

In 1913 Turnbull anonymously donated his Maori and Pacific artefacts to the Dominion Museum (now the Museum of New Zealand Te Papa Tongarewa).
