Louis Stern Mansion, 1884-1929 Louis Stern was the president of the Stern Brothers Department Store. He opened the successful retail company with his brothers, Isaac and Benjamin. The brothers were an important merchandising family who were born to German Jewish immigrants in New York City. In 1884, Louis Stern purchased a 27-foot wide lot between 80th and 81st street on Fifth Avenue. This lot was opposite Central Park. His palace was designed by German architect William Schickel in a French-Gothic inspired fashion. The mansion's ornate facade rose four stories, complete with a stone oriel that supported a stone-balustraded balcony. The doors of the home were clad in bronze and glass. The house quickly became a social hub, hosting parties and social gatherings that brought prominent New York society members to the home. The house was sold to an Adolphus Busch, of St. Louis, in 1911. The mansion was a gift for his daughter Edmee who married art collector Hugo Reisinger. When the couple moved in, Hugo's collection filled the many rooms of the mansion. Paintings of Childe Hassam, Whistler, Carl Melchers, Menzel, Zuegel, and Boecklin lined the walls. The United States entry into World War I prompted suspicion of the Busch's and Reisingers, two wealthy German families. In 1917, an illegal radio receiving station was found on the roof of the mansion. According to a mortified Edmee, their servant Alexander Hugo installed this powerful radio equipment in secrecy under the instruction of her father. The station included a De Forest audion detector, which allowed for the receiving of long-distance messages - likely from Germany's capital in Nauen. Edmee sold the house to a realty company after the war ended. A sixteen-story apartment was constructed a decade later.
