Forgotten Genius Behind Non-Reflective Glass Gets Her Due
Katharine Burr Blodgett invented the non-reflective glass we use every day, but her boss took most of the credit. A century after she became the first woman to earn a physics PhD from Cambridge, scientists are finally telling her story.
In a 1939 Nobel Prize film, chemist Irving Langmuir awkwardly explains a breakthrough invention while wearing a three-piece suit. Then he calls in his colleague, Katharine Burr Blodgett, who steps forward with perfect confidence to describe the science behind non-reflective glass.
Here's what the film didn't mention: Blodgett actually discovered it.
Born into tragedy, Blodgett defied every expectation for an upper-middle-class girl in the early 1900s. She mastered European languages, excelled at a progressive New York girls' school, and graduated from Bryn Mawr College before most women could vote.
During World War I, she proved her genius at the University of Chicago by improving lifesaving gas masks. In 1926, exactly 100 years ago, she became the first woman to earn a physics PhD from the University of Cambridge.
At just 20 years old, Blodgett joined General Electric's Research Laboratory as one of its first female scientists. There, she made groundbreaking discoveries in materials science that quietly transformed everyday life.
Her non-reflective glass coating changed everything from camera lenses to eyeglasses to windshields. The technology still shapes products we use daily, from smartphones to projectors.
But while Langmuir won the Nobel Prize, hobnobbed with celebrities, and even inspired a character in a Kurt Vonnegut novel, Blodgett remained labeled as his "apprentice" for nearly four decades. History largely forgot her name.
Why This Inspires
Today, chemists like Peggy Schott from Northwestern University are digging through archives to recover Blodgett's legacy. Schott once presented a paper at a conference speaking as Blodgett herself, bringing the forgotten scientist back to life.
The Lost Women of Science Initiative is now sharing Blodgett's full story through podcasts and research, revealing a woman whose brilliance equaled any Nobel laureate's. They're uncovering not just her scientific achievements, but the dramatic human story of two equally brilliant minds working side by side in an era that only celebrated one.
A century after her Cambridge triumph, Blodgett is finally stepping out of the shadows and into the spotlight she always deserved.
