Before your grandmother could listen to a radio, someone had to figure out what it should look like. Same with television a couple of decades later. Today, we head back several decades to learn about a prolific artist named John Vassos, who designed some really cool radios and televisions, and a lot of other things (view a gallery of some of them below) — portable record players, juke boxes, restaurants, a fountain pen, even the turnstile still in use at Oriole Park and other major league ballparks. He was also involved in the design of an early fax machine intended to deliver newspapers via radio waves to homes in the 1930s. Danielle Shapiro, who lives in Baltimore, is our guest. A historian of modern design, she's written a biography, "John Vassos: Industrial Design for Modern Life."
