The famous “Joan Anderson” letter from Neal Cassady to Jack Kerouac has been found in Southern California. Cassady apparently wrote the letter to Kerouac in a drug-fueled, sex-crazed haze on December 17, 1950. The rest is literary history.
Kerouac famously called the letter “the greatest piece of writing I ever saw, better’n anybody in America, or at least enough to make Melville, Twain, Dreiser, Wolfe, I dunno who, spin in their graves.” It was the muse that lent the jazzy energy and so-called “stream of consciousness” style to On the Road and the rest of his Duluoz Legend, in which Cassady appears as a clandestine presence (either as Dean Moriarty or Cody Pomeray). But the letter itself disappeared.
