Who they are
Rudolf Kohlrausch collaborated with Wilhelm Weber on electrical measurements that James Clerk Maxwell used when comparing electromagnetic propagation with the speed of light. His place in this account is the experimental groundwork cited by Maxwell, rather than authorship of Maxwell’s field theory. The connection shows how theoretical synthesis depended on earlier quantitative measurement.
He supplies experimental context for the unification of light and electromagnetism.
Selected contributions
- With Weber, provided the electrical measurement cited in Maxwell’s propagation-speed comparison.Source ↗

A Dynamical Theory of the Electromagnetic Field
Maxwell develops a field account connecting electrical and magnetic phenomena. His comparison between electromagnetic propagation and the measured speed of light supports the argument that light is electromagnetic.
