Paul Eisler

Paul Eisler (* 1907 in Vienna, † October 26, 1992 ) was the inventor of the printed circuit board.

Paul Eisler studied at the University of Vienna and graduated as an engineer from 1930. During his studies he worked as editor of a magazine and dealt so well with the printing technology. Due to his Jewish origins, he was forced in 1934 by the Austrian National Socialists rich step, quit his job in 1936, he emigrated to London. Here he experimented with printed circuits and reported to his first patent in 1936 on. However, it was not possible Eisler to find an industrial user for his technique. So they told him the English radio producer Plessey: " Our girls [ in the assembly ] are cheaper and more flexible. "

1939 learned Eisler Harold V. Strong, the wealthy owner of a printing company, know, who saw in Eisler's invention, the chance to enter the defense industry. Eisler gave him a pound sterling the rights to his invention, but the invention in the United Kingdom could not prevail. In February 1943, Eisler registered the patent 639.178 "Manufacture of Electric Circuits and Circuit Components" in London, from where it has been reported routinely even to the U.S. Bureau of Standards.

As will be developed in the early 1940s in the U.S., a proximity fuse for anti-aircraft projectiles, then either there on Eisler's invention back, and it leads to the production stage. Thus, the printed circuit board started out to conquer the world of America. Strong Techno Graph - whose board Eisler worked temporarily - could not enforce its patents and had so little share in the success.

Paul Eisler left Technograph 1957 and worked as a freelancer. He lived until his death in London.
