Charlie Hebdo Editor Made Provocation His Mission

Stéphane Charbonnier, the editorial director of the French satirical newspaper
Charlie Hebdo, was often pictured with his fist aloft.

Mr. Charbonnier, 47, a cartoonist known professionally as Charb, was among 12
people killed Wednesday when gunmen attacked his newspaper’s offices in Paris.
He had been instrumental in a series of defiant campaigns that divided public
opinion — some saw them as powerful stands for free speech, and others as
needless provocations.

He oversaw the publication of a spoof issue in 2011, advertised as guest edited
by the Prophet Muhammad, which led to the paper’s offices being firebombed.

In 2012, Mr. Charbonnier defied the advice of the French government and
published crude caricatures of Muhammad, shown naked and in sexual poses.
Depictions of the prophet, even if reverent, are forbidden under Islamic law.
One of the people killed Wednesday was a police officer assigned to guard the
paper’s offices after those episodes.
