What is "charb"

Stéphane Charbonnier (; 21 August 1967 – 7 January 2015), known as Charb , was a French satirical caricaturist and journalist. He was murdered by Islamist terrorists during the Charlie Hebdo shooting in January 2015.

He worked for several newspapers and magazines, joining Charlie Hebdo in 1992 and becoming the director of publication in 2009. Due to direct support to freedom of speech via Charlie Hebdo, Charb became subject to death threats from Islamists. From the time the magazine was firebombed in 2011, he lived under police protection until his assassination.
