Serge Dassault, French billionaire entrepreneur, dies at 93
French entrepreneur and politician Serge Dassault has died at the age of 93, his family has said.
Mr Dassault led the Dassault group after his father, Marcel's, death in 1986. The group has numerous firms in aeronautics and armaments and owns the French newspaper, Le Figaro.
They put his worth at about $26bn-$27bn (£19.5bn-£20bn).
Mr Dassault was also involved in politics and had served as a conservative senator and a mayor of Corbeil-Essonne, a southern suburb of Paris.
Former French President Nicolas Sarkozy paid tribute to Mr Dassault, saying: "France has lost a great industrialist, and I a friend."
French news channel BFMTV reported that Mr Dassault died after he had a heart attack at the headquarters of the Dassault Aviation group on Monday.
The Dassault Group holds a majority stake in Dassault Aviation, the manufacturer of the Mirage and Rafale fighter jets.
Last year, he was found guilty of fraud by a Paris court after failing to disclose the full extent of his wealth to the tax authorities and fined €2m (£1.75m; $2.3m).
