Ernst Heinrich Weber

Ernst Heinrich Weber ( * June 24, 1795 in Wittenberg, † January 26, 1878 in Leipzig ) was a German physiologist and anatomist.

Life

Weber was the son of the theologian Michael Weber and brother of Wilhelm Eduard Weber (1804-1891) and Eduard Friedrich Weber ( 1806-1871 ). He had visited the Electoral State School in Meissen, studied at Wittenberg, but was evacuated due to the Napoleonic wars to Leipzig, where he joined his studies in 1815 and 1817 habilitation. In 1818 he became associate professor of comparative anatomy and in 1821 Professor of Anatomy ( 1871 ), 1840 Professor of Physiology (up to 1866). Weber had also participated in the organizational tasks of the Leipzig Academy and was in the years 1838/39, 1843/44 Rector of the Alma Mater.

Work

Weber engaged in dealing with the human, comparative and microscopic anatomy as well as the evolutionary history of animals and physiology, especially the physical side; come from him significant studies on the mechanics of walking as well as for pressure, temperature and sense of place in the human skin. Together with Gustav Theodor Fechner (1801-1887) Weber is one of the founders of psychophysics. On the Weber- Fechner law it goes back.

1825 ( and again in more detail in 1834 ), he described the eponymous Weber test for the evaluation of hearing loss. He was the first who determined the lateralization ( unilateral amplification of sound perception) under certain circumstances.

Honor

In 1859 he was inducted into the Order Pour le Mérite for Sciences and Arts. Since 1871 was Weber honorary citizen of the city of Leipzig.

On 23 May 2000 the asteroid ( 11042 ) Ernst Weber was named after him.
