Nicolas Louis Alexandre, Baron de Gunzburg , aka Baron Nicolas de Gunzburg, was a banker and socialite of Russian, Polish, and Portuguese descent, who became an editor at several American publications, including Town amp Country, Vogue, and Harpers Bazaar. He was named to the International Best Dressed List Hall of Fame in 1971.
Baron Nicolas Niki de Gunzburg was born in Paris, France, a scion of a wealthy and influential RussianJewish family, whose fortune had been made in banking and oil. The Gnzburgs, as they were originally known, were ennobled during the 1870s by Louis II, Grand Duke of Hesse and by Rhine, and when family members began spending a great deal of time in France later in the century, the umlaut was dropped and the particle de adopted. Their Hessian title was made hereditary in 1874 by Czar Alexander II of Russia.
