There was a time when almost everyone, from Alexander Graham Bell to the Wall Street Journal, believed there was a supremely intelligent civilization on Mars, one that was probably trying to talk to Earthlings.

He shares many of the most surprising, fascinating, and very entertaining details, including much that had been lost to history, in this book club conversation with Mat Kaplan.
