Lloyd Espenschied (27 April 1889 – June 1, 1986) was an American electrical engineer who invented the modern coaxial cable with Herman Andrew Affel.〔 ==Biography== He was born in St. Louis, Missouri on April 27, 1889.〔 In 1901, he moved to Brooklyn, New York. He became an amateur radio operator in 1904 and later worked for the United Wireless Telegraph Company. He was graduated from the Pratt Institute in 1909 and then worked as an engineer for Telefunken Wireless Telegraph Company.〔 In 1916 while at Bell Telephone Laboratories, he developed the first modern coaxial cable with Herman Affel. In 1924, he invented the radio altimeter.〔(【引用サイトリンク】publisher=Cygnus Interactive )〕〔("Towers Flash Radio Beams To Detect Warplanes" ''Popular Mechanics'', September 1941 )〕 He was an avid genealogist of the Espenschied/Esbenshade/Espenshade family, visiting Germany for the purpose of extensive research. He discovered that all bearers of this name can trace roots back to a common ancestor, Thomas Espenschied, who was born during the turbulent period of the Thirty Years' War (1618–1648), and who lived with his wife Judith (née Lotz) in Kriegsfeld. One son remained in Kiegsfeld. Three sons settled in Siefersheim, which became the starting point for the main branches of the family. Today many families named Espenschied live in Siefersheim. Lloyd Espenschied died on June 1, 1986, at a nursing home in Holmdel, New Jersey. 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「Lloyd Espenschied」の詳細全文を読む スポンサード リンク
