Jerry Seinfeld and Jack Kerouac
We can already hear fans on both sides protesting, but hear us out for a moment. Jerry Seinfeld, the character, was created by Jerry Seinfeld the comedian. Jack Kerouac, meanwhile, was almost always the protagonist of his own novels, although he liked to give himself a pseudonym. Despite the fact that Seinfeld’s work is pretty light and Kerouac’s is all spiritual and liberating and stuff, both appear in their narratives as fairly normal guys and draw inspiration from the stranger antics of their colorful friends. You could also argue that Seinfeld and On the Road both defined an era, albeit in very different ways.
