David Nahmad (born 1947, in Beirut, Lebanon) is a retired fine art dealer and billionaire. A descendant of a Jewish Lebanese art family residing in Monaco and cousin of defunct Edmond Safra, he and his relations are perhaps the single biggest buying force in fine art. As of 2013, David Nahmad and his family's net worth was estimated at $3 billion, ranking him with his family at 377 on the Forbes billionaires list.The roots of the Nahmad family are in Aleppo, Syria, where Sephardic Jewish banker Hillel Nahmad lived until just after the Second World War. Following anti-Jewish violence in 1947, Hillel Nahmad moved to Beirut, Lebanon and when the situation there became difficult, Hillel took his three sons, Joseph (Giuseppe), Ezra and David, to Milan in the early 1960s.
