Georg von Arco
Georg Wilhelm Alexander Hans Graf von Arco ( born August 30, 1869 in United Gorschütz / Upper Silesia, Kingdom of Prussia (now Gorzyce, powiat Wodzisławski, Poland); † 5 May 1940 ) was a German physicist and electrical engineer.
He was Telefunken where he is responsible as Technical Director of a company incorporated in 1903 by two managing companies until 1931 for the scientific and technical fields. Georg von Arco had the lead on the development of powerful transmitters and have been involved together with his teacher Adolf Slaby instrumental in the research and development of high frequency technology in Germany. The Monist and pacifist Arco was 1921/1922 Chairman of the German Monist.

Count Georg von Arco was the son of Count Alexander Karl von Arco on the family's manor in Great Gorschütz ( Upper Silesia ) to the world. He was interested in as a child for machines of all kinds, not studied after graduating from high school at the Wroclaw Mary Magdalene Gymnasium ( 1889), but engineering, but attended mathematics and physics lectures at the University of Berlin and then pursued a career as an officer. For his father, it was obvious that the members of his family either farmers or officers would. After three years in the military, however, changed from Arco his life to study of 1893 at the Technische Hochschule Charlottenburg mechanical and electrical engineering. There he met Professor Adolf Slaby know. Slaby was the only foreigner who was allowed to participate in Marconi's transmission attempts on the English Channel coast.
Based on these experiments served Arco and Slaby in the summer of 1897 the Church of the Savior Church on the Port of Sacrow as an antenna to verify and understand Marconi's experiments. Here, the first German antenna system for wireless telegraphy was built. On August 27, the signal transmission to the 1.6 km distant imperial naval base Kongsnæs succeeded on the opposite shore of the lake in the Virgin Schwanenalle in Potsdam.
A 1928 created by Hermann Hosaeus plaque above the front door of the Campanile points to attempt this. In the center of the panel, which is made of green dolomite, Atlas is the world globe surrounded by lightning and the memorandum: In this place built in 1897 Prof. Adolf Slaby and Count of Arco, the first German antenna system for wireless traffic.
On October 7, 1897 achieved a first radio link from Schöneberg to rank village and already the following summer could be sent down to the around 60 kilometers away Jiiterbog.
AEG
After finishing his studies went from Arco in 1898 as an engineer for Oberspree cable factory of AEG. Initially he worked as a laboratory engineer for testing various types of cables, however, was able to introduce through ongoing contact with Slaby wireless telegraphy at AEG and build.
Telefunken
Patent litigation between Siemens & Halske and AEG meant that at the behest of Emperor Wilhelm II as a joint venture in equal parts by the Society for wireless telegraphy mbH, System Telefunken was founded. The telegram address " Telefunken " quickly became the term for the new company.
Arco was especially in the early days of broadcast systems increase performance and extend the range of the transmitter considerably. To this end, he was transferred to the developed by Max Wien quenched spark transmitter, which had a significantly better efficiency than the pop radio stations by Ferdinand Braun and was also able to transmit on a narrow frequency band.
Successor of Count Arco Telefunken Managing Director in 1931, Dr. Emil Mayer ( 1885-1953 ), who already had to emigrate to the United States as a Jew after the seizure of power by the National Socialists mid-1933 from Germany.
Large radio station Nauen
Count of Arcos greatest merit consisted in the development of in 1906 by Telefunken commissioned in large radio station at Nauen, which he helped the company to rise to a global company. In 1909 he equipped the radio station at Nauen with a deletion radio transmitter, so they went from an experimental station in a station with a regular radio communications. Now contact could be recorded with the German colonies in Africa and the ships of the Imperial Navy. Ten years later (1918 ) the transmitting power had increased tenfold, but this only worked with a whole new transmitter technology, the 1912 imported high frequency machines transmitter with magnetic frequency converter. This permitted for the first time to produce hardly attenuated electromagnetic waves having high performance. This development was very much involved in Arco, also he encouraged after advent of electron tubes experiments so on.
Philosophical and ideological activities
While Adolf Slaby be tried alongside the university, operation of Arco philosophical activity. He joined the Monistenbewegung and the Berlin district of empirical philosophy as well as to the pacifist movement during the First World War, as new as a founding member and Chairman of the Federal homeland. He belonged to the German Monist League, which he chaired from 1921 to 1922. In 1923 he co-founded the Society of Friends of the New Russia, where he celebrated his 60th birthday in Moscow, which in its position was very unusual for someone.
Arco was an Advisor to a member of the Abraham Lincoln Foundation, a German branch of the Foundation the Rockefeller Foundation.
Resting place
Arco was on the West Stahnsdorf in a Erbbegräbnisstätte in the block of the Holy Spirit, Garden Block V, buried. Until the official closure in spring 2011 his grave was an honorary grave of Berlin. At the house Albrecht Straße 49 /50, Berlin -Tempelhof, the Senate attached a plaque. In Berlin -Charlottenburg since 1950 reminds the Arcostraße, the former Havelstraße, the pioneer of radio technology. One exists also in Nauen street named after him.
