OK, raise your hand if you have ever worn a mask over your nose and mouth.

I am hoping for 100% participation. Covid 19, anyone?
But did you ever stop to wonder whose idea it was that we should wear masks in a medical pandemic?
Go back to 1905 and meet Alice Hamilton.
THE EARLY YEARS
Born in 1869 as one of four sisters and a brother, Alice was home-schooled and, by her teenage years, had decided to become a doctor. This was a lofty goal, considering that at this time in American history, very few women had been admitted to medical school.
But, like many strong women, she persevered and was finally accepted at the University of Michigan Medical School. After graduating in 1893, she completed internships at the Minneapolis Hospital for Women and Children and the New England Hospital for Women and Children.
Alice might have chosen to go into a medical practice, but her current interest resided in research. Off she went to Europe to study bacteriology at universities in Germany. Even in Europe, she was an anomaly and sometimes had to sneak into university lectures reserved for male doctors.
By 1897, Alice had returned stateside and completed post-degree studies at Johns Hopkins in Baltimore, Maryland.
Already interested in women’s rights and social justice, she relocated to Chicago and moved into the Hull House, a settlement house run by social activist Jane Addams.
THE CHICAGO YEARS
Her residency in the Hull House changed her life, and she ministered to neighborhood health needs there for the next twenty years. Understanding that poor women had little access to good health care, Alice witnessed firsthand how susceptible those women were to the diseases of city life and how factory work was rife with the spread of infectious diseases.
Working on a hypothesis in 1905 that airborne particles caused many factory diseases, Alice pulled several factory workers and had them blow their noses into Petri dishes. Then she tested their mucus and found almost every sample contained streptococcus bacteria. Concluding that respiratory diseases were transmitted from one sick person to others via droplets in the air, Alice began a campaign that all surgeons wear masks while in surgery to prevent catching or spreading respiratory germs.
The hospitals in Illinois that first adopted this practice saw their respiratory rates drop dramatically. Later, in 1918, when the Spanish Flu entered pandemic proportions, face masks were adopted on a national level to help curb the progression of the disease.
Alice had opened a well-baby clinic at the Hull House, but the mothers insisted on talking about their sick husbands who worked in nearby factories and all had the same symptoms. Alice began to suspect lead and mercury poisoning.
The factory owners, however, were opposed to her theory and altered their workplace data to minimize how much lead and mercury the workers were exposed to.
Alice then took some factory workers out after hours for a couple of beers. Once she gained their confidence, she asked them to sneak factory samples. All the samples she tested contained poisonous amounts of the metals.
Launching a statewide Illinois investigation in 1910, the U.S. Department of Labor concurred that dozens of factory operations had led to lead poisoning of the workers. Within a year, Illinois was one of the states that passed a Workers Compensation Law. A national law was passed a year or so later.
She had taken on industrial diseases and industrial toxins – what next?
THE HARVARD YEARS
In 1919, Harvard University instituted a new Occupational Health curriculum and asked Alice if she would join the school as an assistant professor, lecturing in this department.
There were a few caveats: she could not apply for tenure nor walk with the other (male) professors at graduation and would not qualify for free football tickets. Ahem.
However, Alice Hamilton was now officially the first female professor at Harvard. After retiring from Harvard in 1935, she was recruited as a medical consultant to the U.S. Division of Labor Standards.
THE LEGACY
She died in 1971 at 101, still championing women’s rights and workplace safety, improving community health standards, and living just long enough to see the inauguration of OSHA (Occupational Safety and Health Administration).
Of all my research into Alice’s life, my favorite was the gentleman who asked her in the early 1900s, “But who will darn the socks if we let women become bacteriologists?” Her answer was not recorded, but I envision her arching an eyebrow and replying, “Yes, who indeed?”
In this winter of 2024, whenever you might travel, as you put on a face mask, please whisper – “Thank you, Alice.”
And thank you to blog follower Donna Haarz, who alerted me to Alice’s story.

I am always fascinated by accomplished women whose famous husbands often overshadowed their wives’ contributions to history.
I don’t usually profile a Strong Woman so soon after she has passed, but I am making an exception this month.
