Episode 60 of Books and Ideas is an interview with Matthew Cobb, author of Life's Greatest Secret: The Race to Crack the Genetic Code. We focus on some of the unsung scientists who made essential discoveries. Matthew Cobb was the first person I ever interviewed back in Episode 7, so it was special to have him on to help me celebrate the 9th Anniversary of Books and Ideas.
