After working as an electrical engineer in London on projects such as laying undersea electric cables, he moved to the United States at the age of 26 and became an assistant to Thomas Edison (1887), and later became a professor at Harvard University. He applied complex number theory to AC circuit analysis, contributing to the development of electrical science, and in 1902, independently of O.
