Walldorf (German pronunciation: [ˈvalˌdɔʁf] ⓘ; South Franconian: Walldoaf) is a town in the Rhein-Neckar-Kreis district in the state of Baden-Württemberg in Germany.

In the eighteenth century, Walldorf was the birthplace of John Jacob Astor,[3] who emigrated and became a prominent fur trader in the newly independent United States, establishing a monopoly in North America.

Concentrating on real estate acquisition and investment, and based in New York City, he grew even wealthier and was the patriarch of the wealthy and influential Astor family.

[4] The earliest documentary mention of the settlement occurs as Waltorf in a 770 deed issued by the Abbey of Lorsch.

The area was settled anew by religious refugees, among them the predecessors of John Jacob Astor, Waldensians from Piedmont.
