PARIS: French business executive Serge Dassault, a top aviation and arms industrialist and one of France’s richest men, died Monday in his Paris office. He was 93.

Dassault’s family said he died of a “cardiac deficiency” at the group’s office on the Champs-Elysees Avenue.

Dassault was especially known for the development of France’s Mirage jet fighters, as well as for equipping the French Air Force and other militaries through global sales. He was chairman and CEO of the Dassault Group when he died, and president of honor of Dassault Aviation, which he once led.

The office of President Emmanuel Macron praised a man “who consecrated his life to developing a flagship of French industry.”

Dassault was the son of Marcel Dassault, a survivor of the Nazi death camp at Buchenwald in Germany who founded the aviation company that would form the core of the group’s business.

Like his father, Serge Dassault became a press baron and a politician.

Dassault was fighting a 2017 tax fraud conviction over millions of euros he had kept outside of France. He was also handed preliminary charges in 2014 for alleged vote buying.
