Edith Clarke (February 10, 1883 – October 29, 1959) was an American electrical engineer and academic. Clarke is credited with helping the electric grid grow, with helping that grid remain stable and reliable, and laying the foundation for the smart grid – the grid of the future. She was the first person who used an analyzer to obtain data about power networks. The U.S. Department of Energy calls her efforts “the first step toward smart grid technology. She could be called the Smart Grid’s ‘Founding Mother.’” Clarke was the first woman to be professionally employed as an electrical engineer in the United States and the first female professor of electrical engineering in the country. She was the first woman to deliver a paper at the American Institute of Electrical Engineers. She specialized in electrical power system analysis and wrote the textbook used by power engineers for decades titled ''Circuit Analysis of A-C Power Systems''.
