Paul Gottlieb Nipkow
Paul Julius Gottlieb Nipkow was a German technician and inventor. He invented the Nipkow disk, one of the first successful technologies for television transmission. Hundreds of stations experimented with television broadcasting using the Nipkow system in the 1920s and 1930s, until it was superseded by allelectronic systems in the 1940s.
Nipkow was born in Lauenburg in the Prussian province of Pomerania, now part of Poland. While at school in neighbouring Neustadt , in the province of West Prussia, Nipkow experimented in telephony and the transmission of moving pictures. After graduation, he went to Berlin in order to study science. He studied physiological optics with Hermann von Helmholtz, and electrophysics with Adolf Slaby.
