William Henry Hudson (4 August 1841 - 18 August 1922) was an author, naturalist, and ornithologist. Hudson was born in Quilmes, near Buenos Aires, Argentina.[a] He was the son of Daniel Hudson and his wife Catherine n�e Kemble, United States settlers of English and Irish origin. He spent his youth studying the local flora and fauna and observing both natural and human dramas on what was then a lawless frontier, publishing his ornithological work in Proceedings of the Royal Zoological Society, initially in an English mingled with Spanish idioms. He had a special love of Patagonia. He produced a series of ornithological studies, including Argentine Ornithology (1888-1899) and British Birds (1895), and later achieved fame with his books on the English countryside, including Hampshire Days (1903), Afoot in England (1909) and A Shepherd's Life (1910), which helped foster the back-to-nature movement of the 1920s and 1930s and was set in Wiltshire. Hudson's best-known novel is Green Mansions (1904), and his best-known non-fiction is Far Away and Long Ago (1918), which was made into a film.
