Dr. Erhard Karl Kietz ( * August 22, 1909 in Leipzig Germany — April 6, 1982 in Blütlingen (Wustrow, Lower Saxony) Germany) was a German-born physicist, who researched frequency constancy of video signals. ==Life== Born August 22, 1909 in Leipzig, Germany as the eldest child of mathematics teacher Georg and Anna Kietz, Erhard Karl Kietz attended the Nikolai School in Leipzig and then studied physics, mathematics and chemistry at the University of Leipzig. He was awarded the Doctorate of Science degree in Feb. 1938. Taking on the study of these various science branches enabled him to gain an overview of the various aspects of a situation. Along that line, he also had an independent, critical view of political proceedings. He was very interested in politics but opposed the extremism that he saw arising within nations. During his studies at the University, he was an assistant to Dr. August Karolus,〔(August Karolus )〕 television pioneer, in the laboratory of the Physical Institute of the University from May 1929 to Feb. 1938. From March 1938 until May 1945, he conducted independent research in the same laboratory as physicist in the fields of television, high frequency and amplification technology. Aside from television, his major field of work was the origination of extremely constant oscillation through tuning forks and oscillating crystals. During World War II, he was twice buried in the rubble of bomb attacks on the Institute of Physics at the University of Leipzig. On August 9, 1941, he married Gisela Raschig, born June 1, 1917. On June 15, 1945, they, with their two young children and his lab colleague, Dr. Herbert Mangold, with wife and toddler daughter, were evacuated by the U.S.A. military to the outskirts of Munich. In 1947, their eldest son died from septicemia at the age of five. A middle ear infection during the difficult last months of the war left the bacteria in his system and lack of penicillin in the post-war turmoil rendered a cure unattainable. On May 15, 1956, he, with his family which now included 6 children ages 11 to 9 months, boarded the Dutch freighter (''Witmarsum'' ) of the Independent Gulf Lines in Hamburg, Germany for emigration to the United States. On June 10, 1956, the family arrived in Houston, Texas, from there riding the 441 miles southward by bus to their destination Elsa, Texas. There was no work in his field, however; so in September 1956, the family moved to Altadena, California, on the advice of a German friend, who had emigrated a few years before. Here Dr. Erhard Kietz was employed in the research division of Consolidated Electrodynamics Corporation in Pasadena, where he participated in the design of instrumentation recording equipment under Adrian B. Cook. In January 1959, the family moved to Menlo Park in the San Francisco Bay area, during the development of the area into Silicon Valley. Dr. Kietz joined Ampex Corporation in Redwood City, California, as Staff Electrical Engineer of the Research and Engineering Division headed by Charles P. Ginsburg.〔(Charles P. Ginsburg )〕 From here, he retired as Senior Staff Engineer in 1971〔(AMPEX Video Engineering Dept organizational chart )〕 Unfortunately he felt displaced in American society. Longing for his home country grew; he and his wife considered options to return to Germany. In July 1971, he, along with his two youngest daughters, who were still teenagers (his wife died in a car accident in 1967), departed New York for Bremerhaven on the passenger ship ''Bremen'', locating in Dankoltsweiler (Baden-Württemberg), Germany. He died April 6, 1982, in Blütlingen (Lower Saxony), Germany. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Erhard Kietz」の詳細全文を読む スポンサード リンク
