W. S. Bristowe

William Syer Bristowe (1 September 1901 – 11 September 1979), who wrote under the name W. S. Bristowe, was an English naturalist, a prolific and popular scientific writer and authority on spiders. He was educated at Wellington College and Cambridge University and in 1921 went on a Cambridge University expedition to Jan Mayen led by James Mann Wordie. Two years later he went on another Cambridge University expedition, this time to Brazil.

Late in his life he also had an unexpected but important role in discovering the true story of Anna Leonowens, the 19th century woman whose memoirs inspired a number of dramatic and fictional works, most notably the musical The King and I. Leonowens presented her own account as factual and it was accepted in the west as such, despite being strongly disputed in Thailand. In the 1970s, when Bristowe, a regular visitor to the far east in search of spiders, was researching a biography of Leonowen's son, Louis T. Leonowens, he discovered and published evidence that significant parts of the tale were in fact fictional.
