Charles Joseph Finger (1869 - 1941) was born in Willesden, London. He went to King’s College, London but left without a degree, and went to Germany to study music. His parents emigrated to America, but Charles stayed in Europe and travelled. Between 1890 - 1895 he moved around South America, doing various things to survive: working with gauchos; herding sheep and panning gold. Eventually he made his way north to the United States, and carried on herding sheep but this time in Texas. He became a United States citizen in 1896. He had been writing short stories and doing freelance work as a journalist, and eventually was offered a job on The Mirror, St Louis. The editor encouraged him to write.
Finger wrote many books, drawing on his earlier experiences. A children’s book, Tales from Silver Lands, won the Newbery Medal in 1925. He liked the romantically lawless; many of his books were about highwaymen, vagabonds and pirates. One (as far as I know) was about horses: Give a Man a Horse, which was appeared both in America and his native UK.
