François-Jean de la Barre

He took up Pierre Paul Sirven, another Protestant accused of killing a daughter to prevent her conversion, and got that sentence reversed too.

He took up the Chevalier de La Barre, a young nobleman who was tortured and beheaded at Abbeville in 1776 on a cluster of charges of blasphemy and sacrilege.

Among them, impious songs, mockery of religious rites, and a failure to take his hat off as a religious procession passed.

A copy of Voltaire's own Dictionnaire philosophique was found among the young man's books and was burned with his body.
