description Edith Clarke Overview

Edith Clarke was an American electrical engineer who became the first female professor of electrical engineering in the United States. She is recognized for inventing the Clarke calculator, a graphical device patented in 1925 that solved mathematical equations related to electric power transmission lines up to ten times faster than previous methods. Her work at General Electric and later research focused heavily on analyzing unstable electrical systems. Clarke's contributions provided foundational tools for electrical engineers dealing with large-scale power distribution networks.

help Edith Clarke FAQ

What problem did Edith Clarke's calculator solve?

The Clarke calculator simplified equations used to analyze long electrical transmission lines. Edith Clarke introduced it in 1921, when expanding power networks made faster engineering calculations increasingly valuable.

Was Edith Clarke the first woman employed as an electrical engineer in the United States?

Clarke is widely recognized as the first professionally employed female electrical engineer in the United States. General Electric hired her as an electrical engineer in 1922 after she had previously performed computational work for the company.

What did Edith Clarke do at the University of Texas?

In 1947, Clarke joined the University of Texas at Austin as an electrical engineering professor. She was the first woman to teach engineering there and remained on the faculty until retiring in the 1950s.

How did Edith Clarke influence modern power systems?

Her methods made it easier to model transmission lines and analyze the stability of interconnected electrical networks. That work addressed practical problems created by the large power grids developing during the early 20th century.
