He Invented The Board Inside Every Phone. Nobody Remembers Him

Every phone, laptop and car on Earth runs on a board one man sold for a single pound. In 1936 Paul Eisler, an Austrian engineer who had fled to London, built a radio without a single loose wire. He printed the circuit instead. Telephone companies turned him down, the British government turned him down, and when a company finally took it, he signed away his patent rights for one pound. This is the story of the printed circuit board. It starts in a Hampstead boarding house, passes through the shells of World War Two, and ends inside the device you are holding right now. In this documentary: How people built electronics before printed circuits, and why it was so slow The inventors who came before Eisler, from 1903 to the 1920s Why a Jewish engineer had to leave Vienna, and what he brought with him The contract he signed without reading it How the proximity fuze and the V-1 turned his idea into a weapon The 1948 American decision that put printed circuits into American aircraft instruments The patent fight he lost, and the pizza warmer he invented afterwards Why almost nobody knows his name today If I got a date, a number or a name wrong, tell me in the comments. I read every one and I pin corrections. Parts That Changed History tells the stories behind the chips, machines and software that shaped the modern world, and the people who built them.
