John Jacob Astor (July 17, 1763 – March 29, 1848), born Johann Jakob Astor, was a German-born American businessman, merchant, fur trader, and investor who was the first prominent member of the Astor family and the first multi-millionaire in the United States. He was the creator of the first trust in America. He moved to England as a teenager, where he worked as a musical instrument manufacturer. Astor later went to the United States after the American Revolutionary War and built a fur-trading empire that extended to the Great Lakes region and Canada, and later expanded into the American West and Pacific coast. In the early 19th century, he diversified into New York City real estate and later became a famed patron of the arts.
