1831–1879
Best known for showing that electricity, magnetism, and light are part of the same phenomenon, he helped change physics forever. His work also reached into color vision, the behavior of gases, and even the famous thought experiment now called “Maxwell’s demon.”
Born in Edinburgh on June 13, 1831, James Clerk Maxwell was a Scottish physicist and mathematician whose ideas became central to modern science. He studied at the University of Edinburgh and then at Cambridge, and went on to hold posts at Aberdeen, King’s College London, and later Cambridge, where he became the first Cavendish Professor of Physics.
Maxwell is most celebrated for developing the theory of electromagnetism, showing that electricity, magnetism, and light could be understood together in one mathematical framework. He also made major contributions to the kinetic theory of gases, helped explain the stability of Saturn’s rings, and carried out early work on color vision and color photography.
Although he died relatively young, on November 5, 1879, his influence has only grown. Later physicists, including Einstein, recognized his work as one of the great turning points in science, and his equations remain a foundation of physics and engineering.
