Three Men of the Beagle — Richard Lee Marks

1991 Avon trade paperback, Richard Lee Marks (Cortes: The Great Adventurer and the Fate of Aztec Mexico). Commander of the Beagle, Darwin's famous ship, English aristocrat Robert FitzRoy in 1831 returned from the Fuegian islands (off South America's southernmost tip) with human cargo--four naked, grimy, crouching Yahgan Indians. One of them, a boy nicknamed "Jemmy Button"--clothed, "civilized," catechized and taught the rudiments of English--captured the imagination of Victorian England after FitzRoy and young naturalist Darwin returned Jemmy and the other Yahgans to their homeland in 1834. - Amazon
