A general description of "A Dynamical Theory of the Electromagnetic Field," proposed by Maxwell in 1865.
The Main Idea
Maxwell's theory proposed that electric and magnetic fields move as waves at the speed of light. This was the first time electricity, magnetism, and light had been related in such a way. The theory is also the source of the heavily used Maxwell Equations.

History
When James Clerk Maxwell came out with his paper, "A dynamical theory of the electromagnetic field," in 1865, it was found hard to understand and widely ignored. Even so, it is one of the most important pieces of theory in our history. He himself almost downplayed the importance of his theory, putting more emphasis on Kelvin's vortex theory during his address. Furthermore, it was hard to grasp the concept of intangible fields. Scientists, including Maxwell, tried to picture fields as tangible structures, but to use these mechanical models with the Maxwell equations, they had to be exceedingly complicated.
