..., Ernst Heinrich (1795–1878) German physiologist and psychologist Weber was the eldest of three brothers who all made important contributions to science. He was born at Wittenberg in Germany and became a professor at the University of Leipzig in 1818 , a position he held until his death. Weber is best known for his work on sensory response to weight, temperature, and pressure. In 1834 he conducted research on the lifting of weights. From his researches he discovered that the experience of differences in the intensity of sensations depends on percentage...

..., Ernst Heinrich ( 1795–1878 ). German physiologist , born at Wittenberg; professor of anatomy and later of physiology at Leipzig. He is celebrated for developing methods of measuring the sensitivity of the skin which, together with the work of Gustav Fechner , resulted in the Weber–Fechner law (Δ I / I = constant), where I is the intensity of the sensation and the constant is known as Weber's constant. The constant is different for each sense (for intensity of light, sound, etc.) and tends to increase with ageing, as sensory discrimination becomes...

...at Düsseldorf, and Hans von Weber, who founded his Hyperion-Verlag in Munich in 1906 . The momentous political events that overwhelmed Germany in the 20 th century inevitably affected the book trade. In 1922–3 it was devastated by galloping inflation. Soon after Hitler’s appointment as chancellor, one of the most notorious episodes took place when nationalistically minded students set fire to thousands of Jewish, socialist, and other ‘un-German’ books in various university towns on 10 May 1933 . The works of Freud, Marx, Heinrich Mann, Kurt Tucholsky, and...

...‐Fechner law . This is in fact two laws. Ernst Heinrich Weber ( 1793–1878 ) postulated that ‘just noticeable stimuli’ are proportional to the magnitudes of the stimuli. Gustav Theodor Fechner ( 1801–87 ) quantified this, stating that subjective sensation is proportional to the logarithm of the stimulus intensity. Arcane though this formal definition may seem, the Weber–Fechner law is a crucial link between the physical and perceptual worlds. It implies that what we perceive as a linear scale of tones, say, 1,2,3,4,5 in perceived degrees of lightness,...
