The acclaimed biographer Edmund Morris died earlier this year, at 78, before he could see the publication of his new book, “Edison,” about the brilliant and prolific inventor. David Oshinsky, who reviewed the biography for us, visits the podcast this week to discuss Morris and Edison.

Tina Jordan is on this week’s episode, discussing three new celebrity memoirs, by Demi Moore, Julie Andrews and Carly Simon. “Of the three, the Demi Moore stood out,” Jordan says, “because I’m not used to seeing a book that frank in an era where 99.9 percent of our celebrity memoirs are just vapid.”
