American author, born in Boston, on the 24th of March 1829. He engaged in business in Boston, and in 1853 went to Australia, where he founded the house of Caldwell, Train and Company. He traveled, and at one time endeavored to promote street-railroading in Liverpool and Birkenhead, England, but failed; began lecturing and writing, and became well known on account of his sarcastic criticisms of English society and his personal eccentricities, one of which was, for a time, to refuse to speak to any one. In 1862 he returned to America and made his home in New York. Among his books are An American Merchant in Europe, Asia and Australia (1857); Young America Abroad (1857); Young America in Wall Street (1858); Spread Eagleism, a collection of his public speeches (1859); Young America on Slavery (1860); Downfall of England (1865); Championship of Woman (1868).
