The father of the printed circuit board. He first built a radio using a PCB in 1936, although it would be another five years before he convinced Henderson and Spalding, a lithography company, to invest in his ideas. The US later designed his technology into the proximity fuze, a key World War II technology. Filed his first patent in 1943, which eventually was split into three: 639111 (Three-Dimensional Printed Circuits), 639178 (Foil Technique of Printed Circuits), and 639179 (Powder Printing). Graduated in engineering from Vienna University of Technology in 1930.
