Wilhelm Weber

Wilhelm Weber (1804-1891), was a prominent German physicist who played a crucial role in developing the international system of electrical and magnetic units. Working closely with the legendary mathematician Carl Friedrich Gauss, Weber investigated terrestrial magnetism and co-invented the first practical electromagnetic telegraph in 1833. His most significant achievement was the creation of a highly precise system for measuring electrical charge, current, and resistance based on absolute physical units. This work proved essential for the later development of electromagnetic theory by James Clerk Maxwell. Despite facing political adversity - he was dismissed from his university position for protesting a king’s constitutional violations - Weber remained a dedicated researcher and educator. The standard international unit of magnetic flux, the weber (Wb), honors his memory, reflecting his profound impact on the study of electromagnetism and physical measurements.
