Henry was a banker who, from about 1855, collected Americana and important early printed books. He was unusual among collectors of his age in preparing a catalogue of his library, completed after his death in 1880, with Hazlitt’s assistance. The collection passed to his son Alfred, who enlarged his father's collection of 17th-century books by extensive acquisitions in Restoration drama. Alfred became president of the Bibliographical Society in 1903. On his death, 50 books from his collection formed the Huth Bequest to the British Museum (seebritish library). The rest of his library was sold at Sotheby's in nine book auctions between 1911 and 1920.
