Early Life
Astor was born in Germany in a small town near Heidelberg to parents who owned a butcher shop. At the age of sixteen, Astor moved to London to work for his older brother who was a flute and piano manufacturer. In England he changed his name form Johann Jakob Astor to the anglicized version.
Astor moved to the United States in 1783 after the Revolutionary War. He had intended to work for his brother in a butcher shop in New York City, but became interested in the expanding fur trade in North America during his crossing to Baltimore. After working for his brother for some time, Astor began to purchase raw hides from Native Americans and sell them in Europe at a great profit. When the United States formed the Jay Treaty with Great Britain in 1794, Astor took advantage of new trading markets in Canada and the Great Lakes region. He imported furs from Montreal to New York and shipped them to Europe. By 1800 he had amassed over a quarter of a million dollars and was a major international player in the fur trading industry.
Real Estate Baron
After 1800, Astor started to trade furs, tea and opium to Canton, China. He increased his fortune tremendously. In the 1830’s Astor foresaw the property explosion in New York and condensed his business interests into real estate in and north of Manhattan. Among other investments, he built a farm at Hellgate, a property that ran west of Broadway to the Hudson between 42nd and 46th streets in Manhattan. When he retired from business, Astor became a patron of culture and the arts. He was a Freemason and also President of the German Society of New York (1837-1841).
In proportion to the GDP, Astor was one of the richest people in modern history. He left behind an estate worth 0.9% of the US GDP at the time of his death, roughly equivalent to $276 billion in 2025.
Descendants and the Family Today
One of John Astor’s most famous descendants was his great-grandson John Jacob Astor IV. Like many of the other descendants, John made his fortune in real estate and was the founder of the Astoria Hotel in New York City. This hotel later merged with the Waldorf Hotel, owned by a cousin and rival. Today we know the hotel under the name Waldorf-Astoria Hotel, a leading luxury hotel of the world.

John Astor IV died on the maiden crossing of the Titanic. Other members of the family were prominent in New York aristocracy, and several were involved in philanthropic work. Today the name Astor is still connected with luxury, history and high society, but the family’s wealth has largely been dispersed. The descendants live spread across the world and no longer control vast real estate empires.
