Jean-Jacques Rousseau (28 June 1712 – 2 July 1778) was a Genevan philosopher, writer, and composer of 18th-century Romanticism of French expression. His political philosophy influenced the French Revolution as well as the overall development of modern political, sociological and educational thought.

His novel Émile: or, On Education is a treatise on the education of the whole person for citizenship. His sentimental novel Julie, ou la nouvelle Héloïse was of 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 — exemplified the late 18th-century movement known as the Age of Sensibility, featuring an increasing focus on subjectivity and introspection that has characterized the modern age. His Discourse on the Origin of Inequality and his On the Social Contract are cornerstones in modern political and social thought.

Rousseau was a successful composer of music. He wrote seven operas as well as music in other forms, and he made contributions to music as a theorist.

It was the first time the submission had been used to finish a fight in UFC history. He talked about the move after the fight, "It's something I saw a long time ago on the Internet on video," Jung said. "It's one of Eddie Bravo's moves. It's something I practiced because it looks fun and I do it quite a bit in practice. I have always told people I was going to try it sometime in competition. I wanted to do it in the UFC and I was able to, finally."
