The 1930s were a remarkable decade for research at the General Electric Company, with Katharine Burr Blodgett making groundbreaking discoveries in the field of thin film coatings. Working closely with her boss, Irving Langmuir, who won the Nobel Prize in Chemistry in 1932, Blodgett’s meticulous experiments led to her most significant breakthrough in 1938 – nonreflecting glass. This discovery, dubbed “invisible glass” by the press, propelled Blodgett into the spotlight of both the scientific community and the media.
Blodgett’s journey began with experiments on molecular monolayers, a field that Langmuir had pioneered and for which he was awarded the Nobel Prize. Building on this foundation, Blodgett focused on manipulating monolayers to create multiple layers of substances on solid surfaces. Using a visual tracer like talcum powder to observe molecular motion, she was able to stack monolayers on top of each other, revolutionizing the creation of thin films.
One of the most significant applications of Blodgett’s research was the development of nonreflecting glass. By carefully layering molecules on a glass plate, she created a coating that reduced glare and reflection, enhancing visibility through glass surfaces. This breakthrough had wide-ranging applications, from eyeglasses and camera lenses to windshields and optical devices.
The General Electric Company’s public relations team capitalized on Blodgett’s success, generating widespread media coverage and accolades for her achievements. Newspapers and magazines across the country lauded her discovery of invisible glass, highlighting her scientific prowess and groundbreaking contributions to the field.
Despite the recognition and acclaim she received, Blodgett remained dedicated to her work, displaying unwavering patience and perseverance in her scientific endeavors. Her meticulous approach and attention to detail were instrumental in her success, leading to a series of patents and further advancements in the field of thin film coatings.
As Blodgett’s research continued to make waves in the scientific community, she became a prominent figure in the male-dominated world of science. Her pioneering work in thin film technology laid the foundation for numerous innovations in the years to come, cementing her legacy as a trailblazing scientist and inventor.
In conclusion, Katharine Burr Blodgett’s contributions to the field of thin film coatings during the 1930s were groundbreaking and transformative. Her discovery of nonreflecting glass revolutionized the way we interact with glass surfaces, opening up new possibilities for optical devices and enhancing visibility in various applications. Blodgett’s legacy as a pioneering scientist and inventor continues to inspire future generations in the field of materials science and engineering.
