Jacques Roisen, the former head of the International Diamond Manufacturers Association, died March 26 at age 91.
Born in Antwerp, Belgium, Roisen fled to the U.S. during World War II. After the war and service in the U.S. Army, he joined the diamond business and married his childhood sweetheart, Alice. He soon rose to become head of the Diamond Manufacturers & Importers Association of America, as well as the global body, the International Diamond Manufacturers Association. In 2006, the DMIA honored him at its 75th anniversary dinner.
“Jack was an icon and legend of the diamond industry,” said DMIA president Ronald Friedman in a statement. “[He] was a passionate leader, mentor, and friend. He taught us about business, family, and humanity… We are, in part, what we are today due to the examples that he set for us. His imprint on our industry and on all of us individually will last forever.”
He is survived by Alice, his wife of 67 years; children Shelley and Rita; and four grandchildren.
Funeral services will be held on Tuesday, May 29, at 12 p.m. at the Riverside Chapel in New York City.
