Edith Clarke was an electrical engineer that specialized in electrical power system analysis. She studied mathematics and astronomy in college and graduated in 1908. Clarke then taught mathematics and physics at a private school. She soon after moved on and worked at AT&T for a summer job. In 1918, she continued her career by enrolling in an EE program at MIT. She got her M.S. in electrical engineering the next year. With this, she got a job as a “computer” at AT&T, then in 1921, invented and filed a patent for her Clarke Calculator, a graphing calculator to be used in solving problems with voltage, current, and impendence in power lines. Her technology calculated these problems ten times faster than other systems. Many electrical companies benefited from her invention. Edith Clarke died on October 29, 1959. She led a great life in engineering and many engineers look up to her with the work she did.
