Edith Clarke (born February 10, 1883, died October 29, 1959) was an amazing American electrical engineer and teacher. She focused on understanding how electric power systems work. Many people say she helped create the idea of the 'smart grid,' which makes our electricity network strong and reliable. She was the first to use a special tool to gather information about power networks. The U.S. Department of Energy even called her the 'Founding Mother' of smart grid technology! Her textbook, Circuit Analysis of A-C Power Systems, was used by engineers for many years.
Edith Clarke was also a pioneer. She was the first woman to work as a professional electrical engineer in the United States. She also became the first female electrical engineering professor in the country. Plus, she was the first woman to present a technical paper at the American Institute of Electrical Engineers.

Edith Clarke's Early Life and Education
Edith Clarke was born on February 10, 1883, in Howard County, Maryland. She was one of nine children. Sadly, she lost both her parents when she was 12 years old. Her older sister then raised her. Edith used money she inherited to study math and astronomy at Vassar College. She graduated with top honors in 1908.
After college, Edith taught math and physics. She worked at a private school and at Marshall College. Later, she studied civil engineering for a year. In 1912, she started working at AT&T as a 'computer.' This meant she did complex math calculations by hand! She helped engineers like George Campbell solve problems with sending electricity over long distances. While working, she also studied electrical engineering at Columbia University in the evenings.
In 1918, Edith went to the Massachusetts Institute of Technology (MIT). In 1919, she made history by becoming the first woman to earn a Master of Science degree in electrical engineering from MIT. Her master's project was about how electricity travels through power lines.
Even with her MIT degree, Edith found it hard to get a job as an engineer. So, she joined General Electric (GE) as a supervisor. She led a team of women who performed calculations for turbine designs. In 1921, she left GE for a short time to teach physics in Turkey. This was because she faced unfair treatment at GE; she wasn't allowed to do actual electrical engineering work and earned less than men.
A Trailblazing Engineering Career
When Edith returned from Turkey in 1922, GE finally offered her a job as a salaried electrical engineer. This was a huge step! She became the first professional female electrical engineer in the United States.
Edith specialized in electric power systems. She created special charts that helped GE engineers quickly figure out how electricity flowed through power lines. These charts saved a lot of time, especially during World War II.
The Clarke Calculator and Patents
She also invented the Clarke calculator. This was an early type of graphing calculator. It was a simple tool that helped solve complex math problems about electric current and voltage in power lines. Her calculator could solve these problems ten times faster than older methods! She received a patent for it in 1925. This was one of three patents she earned.
Edith's strong math skills made her famous in her field. She wrote or helped write 18 technical papers while at GE. She was an expert in understanding how electricity behaves in power systems. In 1926, she presented a paper showing how to calculate the most power a line could carry safely. This was very important as power lines grew longer. Two of her papers later won awards from the AIEE.
Improving the Electric Grid
Her work was vital for building and improving the U.S. electric grid in the 1920s and 1930s. In 1930, she led a team at GE that studied how to keep power systems stable. She later moved to GE's Analytical Division, where she analyzed electrical equipment and systems.
Edith also helped design and build huge hydroelectric dams, like the Hoover Dam. She used her electrical knowledge to develop and install the turbines that create electricity from water power. These turbines are still working today!
In 1943, Edith wrote a very important textbook called Circuit Analysis of A-C Power Systems. It was based on her lectures for GE engineers. This book taught a special math method to help engineers understand and fix problems in power systems. It was used to train electrical engineers for many years.
She retired from GE in 1945 and bought a farm. But she didn't stay retired for long!
Teaching at the University of Texas
In 1947, Edith joined the University of Texas at Austin as a professor. This made her the first female electrical engineering professor in the entire country! She taught for 10 years, helping many students and encouraging them to share their research. She retired from teaching in 1956.
Awards and Special Recognitions
Edith Clarke received many honors. She was a Fellow of the American Institute of Electrical Engineers. In 1954, she won the Society of Women Engineers (SWE) Achievement Award. This award recognized her important work in understanding how electricity flows and stays stable. She was also featured in books about important women in history.
Even after her lifetime, Edith's achievements are still celebrated. In 2003, she joined the Maryland Women's Hall of Fame. In 2015, she was inducted into the National Inventors Hall of Fame! The University of Texas at Austin also created an award in her name in 2016 to honor amazing female professors.
Edith Clarke's Lasting Impact
Edith Clarke left a huge mark on the world. She was the first woman to get a Master's degree in electrical engineering from MIT. She was also the first woman to work as a professional electrical engineer in the U.S. and the first female electrical engineering professor. She was even the first woman to present a paper at the AIEE's big annual meeting.
She was also one of the first three women to become a Fellow of the American Institute of Electrical Engineers in 1948. This meant she was recognized as a top expert in her field. She was also the first woman allowed to be a full voting member of the AIEE.
Edith Clarke is remembered for helping our electric grid become stronger and more reliable. She laid the groundwork for what we now call the 'smart grid.' She was the first to use special tools to gather data about power networks. The U.S. Department of Energy truly calls her the 'Founding Mother' of smart grid technology.
In a 1948 interview, Edith shared a powerful message. She said that while there might not be a specific demand for 'women engineers,' there will always be a need for anyone who does excellent work.
