||1839: James Blyth MA, LLD, FRSE FRSSA (4 April 1839 – 15 May 1906) was a Scottish electrical engineer and academic at Anderson's College, now the University of Strathclyde, in Glasgow. He was a pioneer in the field of electricity generation through wind power and his wind turbine, which was used to light his holiday home in Marykirk, was the world's first-known structure by which electricity was generated from wind power.
