Jean Jacques Rousseau (Geneva, 28 June 1712 – Ermenonville, 2 July 1778) was a major philosopher, writer, and composer of the eighteenth-century Enlightenment, whose political philosophy influenced the French Revolution and the development of modern political and educational thought. His novel, Emile: or, On Education, which he considered his most important work, is a seminal treatise on the education of the whole person for citizenship. His sentimental novel, Julie, ou la nouvelle Héloïse, was of great importance to the development of pre-Romanticism and romanticism in fiction.
Rousseau's autobiographical writings: his Confessions, which initiated the modern autobiography, and his Reveries of a Solitary Walker (along with the works of Lessing and Goethe in Germany, and Richardson and Sterne in England), were among the pre-eminent examples of the late eighteenth-century movement known as the "Age of Sensibility", featuring an increasing focus on subjectivity and introspection that has characterized the modern age. Rousseau also wrote a play and two operas, and made important contributions to music as a theorist. During the period of the French Revolution, Rousseau was the most popular of the philosophes among members of the Jacobin Club.
He was interred as a national hero in the Panthéon in Paris, in 1794, sixteen years after his death. Rousseau was born in 1712 in Geneva, since 1536 a Huguenot republic and the seat of Calvinism (now part of Switzerland). Rousseau was proud that his family, of the moyen (or middle-class) order, had voting rights in that city and throughout his life he described himself as a citizen of Geneva.
In theory Geneva was governed democratically by its male voting citizens (who were a minority of the population). In fact, a secretive executive committee, called the Little Council (made up of 25 members of its wealthiest families), ruled the city. In 1707 a patriot called Pierre Fatio protested at this situation and the Little Council had him shot.
Jean-Jacques Rousseau's father Isaac was not in the city at this time, but Jean-Jacques's grandfather supported Fatio and was penalized for it. Rousseau's father, Isaac Rousseau, was a watchmaker who, notwithstanding his artisan status, was well educated and a lover of music. "A Genevan watchmaker," Rousseau wrote, "is a man who can be introduced anywhere; a Parisian watchmaker is only fit to talk about watches." Rousseau's mother, Suzanne Bernard Rousseau, the daughter of a Calvinist preacher, died of birth complications nine days after his birth.
He and his older brother François were brought up by their father and a paternal aunt, also named Suzanne.
