WILHELM EDUARD WEBER (1804-1891), German physicist, was born at Wittenberg on the 24th of October 1804, and was a younger brother of ErnstHeinrichWeber, the author of Weber's Law (see below).
Weber's name is especially known for his work on electrical measurement.
He also carried on extensive researches in the theory of magnetism; and it is interesting that in connexion with his observations in terrestrial magnetism he not only employed an early form of mirror galvanometer, but also, about 1833, devised a system of electromagnetic telegraphy, by which a distance of some 9000 ft. was worked over.
ErnstHeinrich Weber[ernst hIn´rikh vA´bur] Pronunciation Key, 1795–1878, German physiologist.
He was a professor at the Univ. of Leipzig (1821–71) and is known for his work on touch and for the formulation of Weber's law : that the increase in stimulus necessary to produce an increase in sensation is not fixed but depends on the strength of the preceding stimulus.
With his brother Eduard Friedrich Weber (1806–71) he discovered the inhibitory power of the vagus nerve (1845).
