Who is Jim Jones from Travels in Hyper Reality: Essays and what is their importance?

Jim Jones was the cult leader of the People's temple. All the members including Jones committed suicide, presumably as a means of escaping the coming apocalypse. According to Eco, those who knew Jones described him as "an altruistic preacher, a fascinating personality, a convinced integrationist, a good democrat". However, he was also accused of stealing from his followers, using drugs, being sexually promiscuous, and having turned a blind eye towards violence against those who deserted him.
