physician physiologist scientist
Ernst Heinrich Weber was born in Wittenberg on June 24, 1795. Weber was the oldest of the three Weber brothers who throughout their lives were closely linked in their scientific activity. His father serving as a professor at the University of Wittenberg.
He was educated at the University of Leipzig, becoming professor of anatomy there in 1818. He became professor of physiology in 1840.
His careful studies of the sensations of sound and touch were the foundations for the science known as psycho-physics. According to Weber's law, an increase in stimulus necessary to produce a noticeable increase in sensation is not a fixed quantity but is dependent upon the ratio of increase to the original stimulus. Gustav Theodor Fechner (1801 - 1887), German physicist, who restated Weber's law, giving it scientific limits, shares with him credit for the development of psychophysics.
Weber began with research in anatomy and discovered several important structures, some of which still bear his name—for instance, Weber’s ossicle, the Weberian apparatus.
Weber experimentally determined the accuracy of tactile sensations, namely, the distance between two points on the skin, in which a person can perceive two separate touches.
