William Henry Hudson (4 August 1841 – 18 August 1922), known in Argentina as Guillermo Enrique Hudson, was an Anglo-Argentine author, naturalist and ornithologist. Born in the Argentinian pampas where he roamed free in his youth, he observed bird life and collected specimens for the Smithsonian Institution. The Patagonian birds Knipolegus hudsoni and Asthenes hudsoni are named after him. He would later write about life in Patagonia that drew special admiration for his style. His most popular work Green Mansions (1904), a romance set in the Venezuelan forest inspired a Hollywood movie and several other works. Source: Wikipedia (en)
