He was educated at the Collège Louis-le-Grand, where he learned Latin and theology. He later learned English, Italian and Spanish. Though his father wanted him to become a lawyer, Voltaire was drawn to literature and began writing plays and poems in his twenties. His work was liked by aristocratic families because it was witty.
