Scientists Revive Legacy of Forgotten Genius Katharine Blodgett

Katharine Burr Blodgett invented something you've probably used today without knowing her name.

In 1938, this physicist created non-reflective glass at General Electric's lab in Schenectady, New York. Her breakthrough made eyeglasses, camera lenses, and countless other products clearer and more effective. She was GE's first female scientist and held multiple patents for her work with ultra-thin films.

But when historians recently visited her childhood home, they found a plaque honoring a man from 1735 instead. Ask people in her own hometown about Blodgett, and most have never heard of her.

The disappearance wasn't an accident. After her celebrity peak in 1939, Blodgett quietly returned to her lab work while GE's publicity machine moved on. Unlike her boss Irving Langmuir, who won a Nobel Prize and stayed in the spotlight, Blodgett kept experimenting without fanfare.

During World War II, she helped develop smoke screens to protect troops. She worked on semiconductors that would become the foundation of modern electronics. Universities awarded her honorary degrees, and the American Chemical Society recognized her surface chemistry research in 1951.

Yet by the time she retired, her name had already started fading from both GE's records and public memory.

Why This Inspires

Today, the Lost Women of Science Initiative is changing that narrative. Through podcasts, articles, and research, they're documenting Blodgett's full story and asking important questions about how scientific legacies get preserved.

The project reveals that forgetting isn't passive. It's an active process that often overlooks women's contributions while amplifying men's achievements. By examining what happened to Blodgett, researchers are creating a roadmap for ensuring other brilliant scientists don't vanish too.

Her color gauge, which tracked film thickness by matching reflected colors to layer numbers, became a commercial success that's still used in research today. Her methods for creating impossibly thin films opened doors in materials science that future generations walked through.

The wisdom Blodgett shared with young scientists during her career emphasized careful experimentation over flashy results. She believed in the quiet power of persistent, meticulous work.

Now, more than 50 years after her work faded from view, a new generation is making sure Katharine Burr Blodgett's brilliance shines through again.
