English electrical engineer who adapted complex numbers to the study of electrical circuits. He developed techniques for applying Laplace transforms to the solution of differential equations. In addition, he reformulated Maxwell's field equations in terms of electric and magnetic forces and energy flux. His formulation, however, was not as clear as Heinrich Hertz's. Two months after Kennelly, Heaviside suggested than the reason Marconi was able to transmit trans-Atlantic radio waves was that the signal bounced off an electrified layer in the upper atmosphere.
