Abstract
In 1846 Wilhelm Weber (1804–1891) discovered that a characteristic velocity, almost equal to the velocity of light, was a significant constant in the theory of electrodynamics. James Clerk Maxwell (1831–1874) accepted this discovery within his theory of the electromagnetic field (1861–62) and used it as important evidence for his electromagnetic theory of light. This is interesting for a number of reasons.
