Jean Jacques Rousseau was born in Geneva in 1712 to a poor family. He had an unstable childhood and lacked a formal education. As an adult, he tried various careers unsuccessfully before moving to Paris, where he took a mistress and fathered five children he placed in an orphanage. Rousseau gained fame for his 1750 essay winning a prize, and went on to publish influential works on political philosophy and education, including The Social Contract and Emile. However, his controversial ideas led to exile from France. Rousseau suffered from mental illness in his later years and died in 1778.
