George Charles Boldt Sr. (April 25, 1851 – December 5, 1916) was a Prussian-born American hotelier. A self-made millionaire, he influenced the development of the urban hotel as a civic social center and luxury destination.
Career
In 1864, he immigrated to the United States. The Empire State Building now occupies its site at 34th Street and 5th Avenue. He is credited with popularizing Thousand Island dressing at the Waldorf-Astoria Hotel, where he instructed the maître d', Oscar Tschirky, to include it on the menu. The hotel introduced other popular food items, such as Waldorf Salad. Boldt also owned the Waldorf Astoria Segar Company, which imported fine Cuban cigars and was located at the hotel.
