Weber, Wilhelm (1804-1891) Born: Wittenberg, Germany

is best known as the person who deduced that electricity consists of charged particles. Weber held several university appointments including professorships at Gottingen, where he had a very productive collaboration with Karl Gauss. Weber insisted on precision in his mathematical and experimental work. He developed a number of very precise measurement instruments. His efforts helped establish a sound foundation for the study of electricity and magnetism. He is honored by having his name used as the SI unit of magnetic flux density, the weber.
Weber's law
an experimental result that states that the smallest luminance increment ΔL at which a region of luminance L + ΔL is just discernible from a background of luminance L is such that the ratio ΔL/L is constant. See also brightness constancy, simultaneous contrast.
