Arpels was born in
Marseille, France. He was the son of Leon Salomon Arpels, who founded
Van Cleef & Arpels with his son-in-law, Alfred Van Cleef, who was a Dutch diamond-cutter. After his father's death, Arpels joined his brother, Charles Arpels, and Van Cleef to open a boutique store at 22
Place Vendome, in Paris. During the 1920s, American tourists urged the firm to open a New York City branch, and Julien was tasked with opening a store there. With the outbreak of World War II, Julien and his family were forced to leave Europe because of their Jewish lineage. Julien also sent his son, Claude, to
Harvard University so that he would be better prepared to deal with the American clientele. At the firm, Arpels was in charge of the business and managerial end of the firm, while his brother,
Louis Arpels, was in charge of sales. His children, Claude, Jacques and Pierre joined the company's operations during the 1930s and took over its operations. Claude headed the jeweler's American operations, while Jacques Arpels became the chief executive. In 1945, he received the
Legion of Honour in Washington, D.C. from French Ambassador
Henri Bonnet. On April 8, 1964, Arpels died in his apartment at the
Hampshire House. He was 79 years old. == References ==
