Paul Eisler
Paul Eisler (1907 – 26 October 1992, London) was an Austrian inventor born in Vienna. Among his innovations were the printed circuit board. In 2012, ''Printed Circuit Design & Fab'' magazine named its Hall of Fame after Eisler.
==Early life and education==
He graduated in engineering from Vienna University of Technology in 1930. Being Jewish, antisemitic German-Nationalist organizations prevented him from getting an engineering job in Vienna, so he obtained employment with the English recording technology firm (Gramaphone Company, EMI from March 1931) operating under its His Master's Voice brand in Belgrade. His task there was to eliminate radio interference on the music broadcast system on trains running from Belgrade to Niś.〔 The project was a technical success but a financial failure because the Serbian railroad could only pay HMV by barter in grain, not pounds sterling, due a foreign exchange crisis. As a result, he had to return to Vienna. He was still prevented from working as an engineer, but he found work as a journalist and printer, first at Randfunk (which developed a low-cost method of tabulating a radio program guide at the printer) and eventually landing at a social-democratic publisher, Vorwärts. The experience in printing proved crucial later. However, after the 1934 putsch by Austrian fascists and due to social-democratic nature of Vorwärts it was shut down.〔 Working independently, he patented some ideas from his doctorate at the university (on graphical sound recording and stereoscopic television) and leveraged them to obtain a visa to visit England to offer the patents to companies there in 1936.〔 His first cousin, Philipp Fehl, contacted Eisler upon arrival as a refugee in England and Eisler helped to make sure that Fehl's father left Vienna alive after his release from the Dachau concentration camp.
