there is no definitive evidence to suggest that Jack Kerouac, the American writer and key figure of the Beat Generation, had schizophrenia. He is not known to have been diagnosed with this particular mental illness.
However, it is essential to note that Kerouac did struggle with various mental health issues throughout his life, including depression and alcoholism. His novel "On the Road" and other works often explore themes of restlessness, self-destructive behavior, and a search for meaning, which could be seen as reflections of his own struggles.
It's essential to treat mental health matters with sensitivity and respect, and speculating about historical figures' specific conditions without proper evidence or a formal diagnosis is not advisable.
For the most accurate and up-to-date information, it's recommended to consult reputable biographies, scholarly sources, or information released in 2023.
