thumb Benjamin Garver Lamme (January 12, 1864 – July 8, 1924) was an American electrical engineer and chief engineer at Westinghouse, where he was responsible for the design of electrical power machines. Lamme created an efficient induction motor from Nikola Tesla's patents and went on to design the giant Niagara Falls generators and motors and the power plant of the Manhattan Elevated Railway in New York City. ==Biography== Lamme was born on a farm near Springfield, Ohio, on 12 January 1864. From an early age he tinkered with machinery and made experiments of his ideas on the Lamme family farm. Lamme liked things that rotated, especially at high speed. In later years he was able to solve complex problems in his engineering work using mental calculations. Lamme graduated from Olive Branch High School near New Carlisle, Ohio in 1883〔(【引用サイトリンク】 Olive Branch School Preservation Society )〕 and subsequently entered Ohio State University and graduated with an engineering degree in 1888. In early 1889, Lamme read an article about Westinghouse forming the Philadelphia Natural Gas Company of Pittsburgh. Westinghouse hired Lamme and within a few months transferred him to the Westinghouse Electric Company. Lamme took over the stalled project of developing a practical version of Nikola Tesla's patented induction motor from Westinghouse engineer Charles F. Scott and came up with a more efficient cage winding design.〔Donald Scott McPartland, Almost Edison: How William Sawyer and Others Lost the Race to Electrification, ProQuest - 2006, page 325〕 Over a period of several years, he designed a variety of electrical motors and generators. Among his eight US patents were inventions on induction motors, electrical ship propulsion, and Gyroscopic stabilizer systems. He designed the single-reduction motor for street railways (replacing the double-reduction motors), the Rotary Converter, railroad electrification systems, the Westinghouse Type C Induction Motor, and the first 5000 kW generators for the giant hydroelectric generators in the Adams Power Plant at Niagara Falls, for many years the largest power station in the world. Bertha Lamme Feicht worked alongside her brother in the design of the turbogenerator at Niagara Falls. Operation began locally in 1895 and power was transmitted to Buffalo, New York, in 1896.〔(Electricity and its Development at Niagara Falls ) at ublib.buffalo.edu〕 Lamme spent many years developing advanced analysis and computational methods for designing and predicting the performance of electrical machines, doing much of the work at night because he had other duties assigned to him during the day.〔Lamme, Autobiography〕 Among other available employees, no one else seemed able to do the computational work, so Bertha, who like her brother Benjamin had an engineering degree from Ohio State University, was recruited to aid with the computation.〔Lamme, p. 91〕 After a few years, she left Westinghouse to get married. The importance of Lamme's methodology was realized in 1893 when Westinghouse began designing the first Niagara Falls 5000 kW generators. Lamme designed much of the apparatus for the Westinghouse exhibit at the Columbian Exposition in Chicago in 1893, including alternating-current generators, induction motors, and rotary converters. In addition to his design work on the Niagara Falls alternators, Lamme designed the “monster machines” for the power plant of the Manhattan Elevated Railway in New York City. Lamme became chief engineer at Westinghouse in 1903 and held the position for the rest of his life. The New York, New Haven and Hartford Railway adopted the Lamme’s single-phase electric rail system in 1905. In 1915, Lamme was nominated by the American Institute of Electrical Engineers (AIEE, in 1963 merged into IEEE) and was appointed by the Secretary of the Navy to represent the AIEE on the Naval Consulting Board.〔(【引用サイトリンク】title=Institute Representatives )〕 Lamme died July 8, 1924 in Pittsburgh, Pennsylvania, at the age of 60. In his will, he established the AIEE Lamme Medal to recognize members of the AIEE for 'meritorious achievement in the development of electrical apparatus or machinery.' His will also provided for a gold medal to be awarded by the American Society for Engineering Education for accomplishment in technical teaching. 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「Benjamin G.
