In this episode, we revisited our Summer 2015 magazine story(bit.ly/sternglass_pittmedmag), featuring the University of Pittsburgh’s late, great Ernest Sternglass. His work made possible the first videos from the moon, and he pioneered digital radiology. His activism helped stop atomic bomb testing. His correspondence with Albert Einstein has been called one of the 20th century’s most important disregarded pieces of science. Sternglass led an extraordinary life. Written by Michael Fitzgerald. Produced by Elizabeth Martinson with Elaine Vitone. Our executive producer is Erica Lloyd. Sound effects courtesy of NASA and freesound.org. And special thanks to Pittsburgh’s own Skyler Brimmeier, a.k.a Sleep Movies (bit.ly/2SCexT1), for our music. Image by NASA.
