Life

Radio receiver Seibt 214 W (1934)

He studied at the philosophical faculty of the University of Rostock and obtained his doctorate with a dissertation on electrical wire waves taking into account Marconi's wave telegraphy . As an assistant to Adolf Slaby at the TH Charlottenburg , he received his doctorate in 1902 with a thesis on mathematical processes at transmitting and receiving stations.

He then worked briefly as technical manager with Karl Ferdinand Braun at Siemens & Halske , the Telefunken company, the experimental office of the telegraph administration and the Deutsche Amalgameted . From 1909 he was chief engineer at Lee de Forests Radio Telephone Company.

In 1910 he founded his own company at Hauptstrasse 9 in Schöneberg near Berlin. He gained an international reputation with precision rotary capacitors by milling the plates out of one piece. Whole measuring instruments followed, the need for which rose sharply in the First World War. Around 1915, at the beginning of the radio era, its dual-circuit detector-receiver and its triple clip-on crystal detector were outstanding.

After the First World War, telephones and receivers for wireless telegraphy came into the production program. Seibt soon set up his own general agencies in England, Holland, Italy, Austria, Romania, Switzerland, the Scandinavian countries and Spain.

In March 1923 he participated with Siegmund Loewe and his colleague Eugen Nesper in the founding of the first association of German radio amateurs, the German Radio Club e. V. (DRV), which served to better assert their interests, such as the popularization of radio systems. Nesper became chairman of the board. This resulted in a tense relationship between the radio amateur movement and the Reichpost with its "Reichs-Rundfunk-Kommissar" Hans Bredow .

His membrane loudspeaker manufactured in 1923 - called the butter dish - was the first of its kind in Germany. It was a loudspeaker with a membrane made of thin sheet aluminum in a round metal housing that was open at the top. As early as 1913, he had described the mode of action of a freely radiating conical membrane and the problems with the sound quality in a laboratory protocol.

In 1927 he hired Otto Griessing , who rose to the position of chief designer and in 1933 developed the first people's receiver .

Radio Pierrette by Dr. Georg Seibt Nachf. - built in 1948/49

His company achieved a turnover of 16 million RM in 1929 with around 1200 employees, but ran into liquidity problems in the same year. In 1931 the company was converted into a public limited company. In 1933 sales were only 7.2 million RM and in 1934 5.8 million RM, whereupon the company had to register a settlement. Seibt died in the same year.

Only the armaments contracts that began in 1935 were able to save Seibt AG from the closure of operations. The last radio models were produced in 1939/40. In 1942 Seibt AG only worked for the military sector and merged with the optics company CA Steinheil & Sons in Munich. After the Second World War she was named Dr. Georg Seibt Nachf. (OHG), continued in Berlin-Schöneberg, until the company was liquidated in 1949/50 following a settlement procedure. In East Germany, the Zittau plant was initially renamed Radio- und Metallwerke Zittau and later Funkwerk Zittau-Olbersdorf , where a number of devices were made until 1952/53.

The Seibtweg in Berlin-Zehlendorf is named after him.
