Katharine’s relatives lead the production team to a collection of papers and artifacts stored in a New England storage unit, revealing an inner struggle she kept carefully out of sight – even as she was making history in the laboratory.

The 1930s prove to be an exceptional decade for research at The General Electric Company. Katharine Burr Blodgett works closely alongside her boss, Irving Langmuir who, in 1932, wins the Nobel Prize for Chemistry. In 1938, Katharine’s meticulous experiments with thin film coatings on solid surfaces lead to her most important breakthrough: non-reflecting glass. The General Electric Company’s public relations machine kicks into high gear. Katharine becomes an overnight sensation, both in the scientific community and in the press, which dub her discovery “invisible glass.” The assistant to the Nobel Prize winner, long invisible herself, takes center stage.

The only woman in a laboratory filled with men, Katharine Burr Blodgett soon becomes indispensable as an assistant to The General Electric Company’s most famous scientist, Irving Langmuir. Their working relationship is an elegant symbiosis: her forte is experimentation, his is scientific theory. We follow their partnership as they successfully find ways to build a better lightbulb but Langmuir stumbles with an off-the-wall theory of matter. All the while, Katharine builds her life in Schenectady: going to church, making new friends, falling in love. In 1924, she embarks on a new journey to the University of Cambridge, where she studies with some of the most prominent physicists of the 20th century.
