Oskar Dieter Alex von Rosenberg-Redé, 3rd Baron von Rosenberg-Redé (4 February 1922 – 8 July 2004), also known as Alexis, Baron de Redé, was a prominent French banker, aristocrat, aesthete, collector, and socialite. In 2003, he was appointed a commandeur of the Ordre des Arts et des Lettres for his restoration of the Hôtel Lambert, where he was known for hosting opulent costume balls. Involved in horse racing, in 1972 he won the Prix de Diane and came in second at the Prix de l'Arc de Triomphe. Early life and education Oskar Dieter Alex von Rosenberg-Redé was born in Zurich, Switzerland on 4 February 1922, the third and youngest child of (1878–1939), a banker from Austria-Hungary. His father – whose mother was Hungarian and father unknown – had been adopted by a banker named Rosenberg and made a citizen of Liechtenstein, then created a baron in the Hungarian nobility by the Emperor of Austria in 1916. Redé's mother was Edith von Kaulla (1890—1931), a member of an ennobled German Jewish family that had been part-owners of the Royal Württemberg Court Bank (″Königlich Württembergische Hofbank″, founded by Karoline Kaulla and Raphael Kaulla). He had two siblings. Born in 1919, his brother Hubert von Rosenberg-Redé was the heir to the barony, while his sister Marion von Rosenberg-Redé (born 1916) was handicapped. The children were brought up Protestant and raised in a 16-room hotel suite at the Dolder Grand Hotel in Zurich, attended by a great many maids, nannies, porters, and valets. Their father visited occasionally. As their finances decreased with the onset of World War II, they moved into a two-bedroom suite. Diagnosed with leukemia, their mother died in 1931, when Redé was nine years old. Redé and his brother were then sent to be educated together at Institut Le Rosey in Switzerland. On account of bankruptcy, his father committed suicide in 1939 at the family's estate (Villa Rosin) in the Austrian town of Kaumberg. Living on an insurance policy income of $200 a month, Redé moved to New York City, where he briefly attempted to acquire American citizenship. He traveled to California to work for an antique dealer, where he earned money to support his sister and befriended Elsie de Wolfe (known as Lady Mendl), as well as Salvador and Gala Dalí. He returned in New York in 1941. His brother committed suicide in 1942 in Hollywood, California, whereupon Redé became
