Stéphane Hessel, a hero of the French Resistance who, more than 60 years later as a nonagenarian, marshaled the same defiant spirit in a manifesto that inspired social protesters in Europe and the United States and became an international publishing phenomenon, died on Tuesday in Paris. He was 95.

His death was confirmed by his son Antoine, a cardiologist.

Mr. Hessel’s life had many notable chapters, including a childhood peopled by European intellectuals, an escape from a German concentration camp, and stints as a diplomat at the United Nations and elsewhere.

But he was not widely known until October 2010, when he published “Indignez-Vous!” — a 4,000-word pamphlet that urged young people to revive the flame of resistance to injustice that burned in himself and others during World War II, this time in peaceful rebellion against what he termed the dictatorial forces of international capitalism, and to reassert the ideal that the privileged class must help the less fortunate rise.

In particular, Mr. Hessel’s diatribe took aim at France’s treatment of illegal immigrants, the influence on the news media by the rich, the shrinking social safety net and, especially, Israel’s treatment of the Palestinians.
