PBS - How We Got to Now (2014) Part 5 Cold

How We Got To Now with Steven Johnson reveals the story behind the remarkable ideas that made modern life possible; the unsung heroes that brought them into the world – and the unexpected and bizarre consequences each of these innovations has triggered.

Part 5: Cold

Only in the last 200 years have humans learned how to make things cold. Steven Johnson explains how ice entrepreneur Frederic Tudor made ice delivery one of the biggest export business in the U.S. and describes the place where Clarence Birdseye, the father of the frozen food industry, experienced his eureka moment. He also travels to Dubai to see how mastery of cold has led to penguins in the desert. From IVF to food, politics and Hollywood to human migration, the unsung heroes of cold have led the way.
