Weber, Wilhelm Eduard (vĭlˈhĕlm āˈdōärt vāˈbər) [key], 1804–91, German physicist. He was professor (1831–37, 1849–91) at the Univ. of Göttingen, where he worked with C. F. Gauss on terrestrial magnetism and devised an electromagnetic telegraph. He introduced the absolute system of electrical units. The coulomb was once known as the weber; now the weber is a magnetic unit. With a brother, E. H. Weber, he wrote (1825) a book on wave motion; with another brother, E. F. Weber, he made a study of walking.
