Widely regarded as one of France's most brilliant, if provocative, lawyers, Verges made a name for himself by accepting clients spurned by others as impossible to defend.
The lawyer died on Thursday in the Parisian house where 18th century philosopher Voltaire once lived, according to his publisher Pierre-Guillaume de Roux.
"Like Voltaire, he cultivated the art of permanent revolt and volte-face," his publisher said.
In the 1960s, Verges defended Algerians fighting for independence at a time when an end to French rule in the North African country was opposed by some sections of French society.
Verges told Reuters in an interview in 2002. "Now I am simply doing my job as a lawyer."
