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.

Clean

Dirty water has killed more humans than all the wars of history combined, but in the last 150 years, a series of radical ideas, extraordinary innovations and unsung heroes have changed our world. Steven Johnson plunges into a sewer to understand what made a maverick engineer decide to lift the city of Chicago with jackscrews in order to build America’s first sewer system. He talks about John Leal, who deliberately “poisoned” the water supply of 200,000 people when, without authorization, he added chlorine, considered lethal in 1908, into Jersey City’s water and made it safe to drink. This isn’t only about the world becoming a cleaner place — the iPhone, the subway, flat screen TVs and even the two piece swimsuit are the result of the valiant efforts of the unsung heroes of clean.

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.
