As teenagers in the 1960s, they began to deal in art. Ezra and David used free-time after school to trade on the Italian stock market. At a
Juan Gris exhibition in Rome organised by cubist dealer
Daniel-Henry Kahnweiler, Ezra and David bought two works – the only pieces sold. Kahnweiler befriended them, selling them works by
Pablo Picasso,
Georges Braque, and Gris. With the emergence of the
Red Brigades terror group in the 1970s, Milan was perceived as too dangerous, and the family moved again. Joseph and Ezra headed for
Monaco, and David to New York City. Helly Nahmad Gallery, located at the luxury
Carlyle Hotel on
Madison Avenue, is a company run by David’s son
Hillel "Helly" Nahmad, who took over his father’s earlier Davlyn Gallery in 2000. In 2013 the Gallery was raided by the
FBI in connection to a sweep of gambling and money laundering operations of the
Russian Mafia. Jeffrey Deitch, art dealer and former director of the
Museum of Contemporary Art, Los Angeles, once described the Nahmads as "like a major brokerage firm in the stock market", adding: "The market needs a force like this to function." According to the cartel presented at the
Beyeler Fondation in
Basel during The Young Picasso Periods Blue and Pink exhibition, the Nahmad collection now owns
Young Girl with a Flower Basket (1905), bought in 2018 for 115 million dollars at the Rockefeller sale at Christie's. ==
