John Basinger, an actor and college professor widely believed to be the only person ever to have memorized all 12 books of John Milton’s epic poem “Paradise Lost” — a feat he turned into a one-man show that inspired research into the workings of memory — died on May 29 in Brookings, S.D. He was 92. His death, at a hospice facility, was from complications of pneumonia, his wife, the film historian Jeanine Basinger, said.
