Christian August Hausen
Christian August Hausen (1693–1743) was a German mathematician who is known for his research on electricity. Biography. Hausen studied mathematics at the University of Wittenberg and received his master's degree in 1712. He became an extraordinary professor of mathematics at the University of Leipzig at the age of 21 and later (1726) became an ordinary professor. Hausen also researched electrical phenomena, using a triboelectric generator. In the introduction to his book on this subject, "Novi profectus in historia electricitatis", published posthumously, Hausen states that he started these experiments shortly before his death. Hausen's generator was  similar to earlier generators, such as that of Francis Hauksbee. It consisted of a glass globe rotated by a cord and a large wheel. An assistant rubbed the globe with his hand to produce static electricity. Hausen's book describes his generator and sets forth a theory of electricity in which electrification is a consequence of the production of vortices in a universal electrical fluid.
