August Uno Lamm (May 22, 1904 – June 1, 1989) was a Swedish electrical engineer and inventor.〔 He was sometimes called "The Father of High Voltage Direct Current" power transmission.〔William R. Gould, "August Uno Lamm", in ''Memorial Tributes, Volume 5, 1992'', National Academy of Engineering. retrieved from http://books.nae.edu//books/0309046890/html/145.htm" August 24, 2005〕 ==Biography== Lamm was born in Gothenburg on May 22, 1904 to Fredrik Hjalmar Lamm and Aino Maria Lovisa Wilhelmina Wijkander. He obtained his master's degree at the Royal Institute of Technology in Stockholm in 1927. After a short time in compulsory military service he joined ASEA, the Swedish electrical conglomerate, initially working in their training program. In 1929 he was made manager of the project to develop a high-voltage mercury arc valve. Valves at the time operated only at about 2500 volts, and if higher-voltage valves were available they could have practical use in the transmission of large quantities of electric energy over long distances. In 1943 Lamm obtained his Ph.D. from the Royal Institute of Technology, studying part-time while developing the mercury arc valve. After twenty years or so of development work to produce a valve with the necessary rating for HVDC transmission, ASEA obtained a contract for the HVDC Gotland project in 1950, which when completed in 1955 became the first modern fully commercial HVDC system. In 1955 Lamm was made head of the ASEA project to develop Sweden's first commercial nuclear reactors. Lamm was appointed by ASEA in 1961 to work with General Electric on the Pacific DC Intertie project, which combined AC and HVDC transmission systems to move electrical energy from the hydroelectric generators of the Pacific Northwest to consumers in southern California. By the end of 1964 Lamm had moved to southern California.〔 From 1967 to 1988 he served as an IEEE director at large. He died on June 1, 1989 in Burlingame, California. 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「Uno Lamm」の詳細全文を読む スポンサード リンク
