Dean Olsher is a writer, broadcaster, and composer. After years as NPR News’s culture correspondent in Washington, DC, he went on to create and host The Next Big Thing, which was distributed nationally by PRI. During an appointment as a visiting professor at NYU’s Arthur L. Carter Journalism Institute, he created a popular course called The Medium Formerly Known as Radio. His book From Square One: A Meditation, with Digressions, on Crosswords (Scribner) claims to be about puzzles but is really about human psychology. And music.
