Katharine Blodgett: First Woman PhD Physicist at GE

A brilliant young scientist stood just 5 foot 2 inches tall, but her impact on modern technology would tower over generations to come.

Katharine Burr Blodgett joined General Electric's research lab in Schenectady, New York, in the early 1920s as one of the company's first female scientists. She wasn't just filling a seat—she was about to revolutionize how the world saw things, literally.

Working alongside Irving Langmuir, who would win the Nobel Prize in 1932, Katharine brought something special to their partnership. While Langmuir excelled at scientific theory, she had an extraordinary gift for hands-on experimentation that made their collaboration remarkably productive.

Together, they tackled everything from building better lightbulbs to understanding the fundamental nature of matter. Their work laid the groundwork for innovations we use every day, from anti-reflective coatings on glasses and camera lenses to advances in molecular science.

In 1924, Katharine took her talents international, heading to the University of Cambridge to study with some of the 20th century's most prominent physicists. She would go on to become the first woman to earn a PhD in physics from Cambridge, proving that brilliance knows no gender.

Why This Inspires

Katharine didn't just survive in a world that wasn't built for her—she thrived and left it better than she found it. At a time when most women scientists left their careers after marriage, she stayed for decades, doing what many consider the most important scientific work of any female researcher at GE.

Her lab notebooks may have been lost to history, but her legacy remains visible every time we look through a non-glare screen or camera lens. She showed that persistence, talent, and partnership can create breakthroughs that last generations.

Katharine Burr Blodgett proved that the best science happens when we make room for every brilliant mind at the table.
