Brilliant Dr Alice Hamilton, USA

Alice Hamilton (1869-1970) grew up in a cult­ured family on a large Fort Wayne Ind. estate. Her fath­er wanted home-schooling for his daughters, but eventually Alice decided to become a doc­tor anyhow. She studied phys­ics and chemistry with a local teach­er, took biol­ogy and anatomy courses, ov­ercame her father’s objections and enrolled in the top class Uni of Michigan Med­ical Sch­ool in 1892. There were c4,500 fe­male doc­tors in the US then, mostly trained at women’s medical colleges.

After graduating from Michigan, Dr Hamilton interned at N.W Hosp­ital for Women and Children, Minneapolis and then at the New England Hospital for Women & Children Bos­ton. Hamilton had already decided on a career in research rather than clinical med­ic­ine, but she wanted some clinical exper­ience. In 1893, Hamilt­on accepted a path­ol­ogy re­sear­ch position at Johns Hopkins Medical School. Then she taught path­ology at Women's Med­ic­al School of N.W Uni Ch­icago and was soon was appointed Pathology Prof there.

She lived for years at Hull-House Chicago, a settlement staff­ed by university graduates who helped immig­r­ants and the poor, via social research and reform. Hull-House people investigat­ed family in­come, school truancy, sanitation, TB and issues affecting community health and safety. And they helped organise Lab­our unions when many wealthy Americans opp­os­ed workers’ rights. And she later work­ed as a bact­er­iol­og­ist at Chicago’s Memorial Institute for Infect­ious Diseas­es.

Hull-House, Chicago

In the 1902 summer holidays, Dr Hamilton found Chicago in a severe typhoid fever epidemic. So she needed to explain typhoid, ident­ifying the in­eff­ec­tive sewage dis­­posal in 19th Ward, outdoor toilets, broken plumb­ing, standing water and flies. Tests on flies captured near filthy toi­l­ets ind­ic­at­ed the presence of the typhoid bacillus. But blame properly fell on broken wat­ermains that spewed sewage into water pipes, despite Chicago Board of Health denials.

That same year, when the Women’s Medical School of N.W University closed, Al­ice became a bact­er­iologist at Chicago’s new­ly opened Memorial Institute for Infect­ious Diseas­es. The U.S saw rapid industrialisation and by 1900 had become the world’s most industrialised nat­ion. The growth occur­red in mining, manufact­ur­ing, transport and commerce, enabled by cheap energy, better technol­ogy, grow­ing transport­, investment capital and cheap labour. But it al­so pro­duced low wages, job insec­urity, poor working con­ditions, ind­ust­rial accid­ents & disease.

Industrial poisoning was problematic since it could take years to emerge. Most employees & employers were ign­or­ant of the dang­ers from chemicals, and few factories emp­loyed doc­tors to mon­itor wor­k­er health. In any case, which workers would complain, risking their jobs?

Ill­inois' governor app­ointed Dr Hamilton to the Illinois Commission on Occupat­ional Dis­eases (1908-10). Indus­trial tox­icol­ogy was little und­erstood, so the commiss­ioners asked her to study diseases where high mor­tality rates were found: in painting trades, lead and en­am­el­ware industries, rub­ber production, explosives and munit­ions. The most widely used poisons were lead, arsenic, zinc and carbon mon­oxide.

From 1911-20, she became a special investigator for the U.S. Bureau of Labour Statistics, examining the manufacture of white lead and lead ox­ide in paint pigments. The team visited factories, read hospital rec­ords and interviewed unionists to uncover lead poison­ing cases. She discovered 70+ dangerous processes that caused high lead poisoning. During this time, Hamilton became a noted expert in industrial medic­ine. Harvard Uni quickly placed her on fac­ulty in the School of Public Health in In­dustrial Medicine, making her the first-ever woman lecturer at Har­v­ard. This made Dr Hamilton a famous expert in industrial medic­ine.

The Illinois report on industrial disease led to state legisl­at­ion, Oc­c­upational Disease Law (1911), requiring employers to: end work­ers’ ex­posure to risky chemicals, offer monthly medical exams for work­ers in dangerous trades, & report diseases to the Dept of Fact­ory Inspection. Soon Charles Neill, Comm. of Labour in Dept of Comm­erce asked her to do nationally what she’d done in the state, first in the lead trades, then in other poisonous trades.

In WWI she also investigat­ed the pois­onous effects of man­­ufacturing expl­os­ives on workers, as requ­ested by National Research Council. Factories had sprung up to produce TNT, picric acid and merc­ury fulminate. Her rep­or­ts on the dan­gers in war-industries led to the adoption of many safety proced­ures. After the war, Hamilton discussed mercury poisoning in the felt-hat industry, the mercury causing wild jerk­ing of limbs, and mental ill­ness. And workers who made matches were subject to an industrial dis­ease that result­ed from fumes of white or yellow phosphorous which pierced the jaw bone.

Hamilton’s impressive work was soon recognised abroad. From 1924 she ser­ved a 6-year term on the Health Committee of the League of Nations. She was invited by the Soviet Public Health Ser­vice, and toured a Moscow hospital that was the first-ever facility devoted to occup­at­ional disease. Appropriately she wrote Indus­trial Poisons in U.S (1925). And she pub­lish­ed Ind­ustrial Toxicology (1934), studying anil­ine dye, carbon mono­xide, mercury, benzene and other toxic chemicals for the Dept of Lab­our. Over the years, her many reports for the Federal gov­ernment dram­at­ised the high mortality rates for industrial workers, bringing major legislative changes.

Dr Hamilton first encountered carbon disulfide years earlier when she had stud­ied rubber making. Then in 1935, Hamilton conduct­ed a study of vis­c­ose rayon manufacture. This new ind­ustry used two dan­g­erous chem­icals: 1] carbon di­sul­fide, which poisoned the central nervous system, leading to mental disease, blindness and paral­ysis. And 2] hydrogen sulfide, a pow­er­ful asphyxiating toxin. Car­bon disulfide received lit­tle Amer­ican attention until Hamilton examined serious illness­es am­ong U.S viscose rayon workers. The Dept of Labour appointed her Ch­ief Med­ical Consultant, with her results pub­lished in Occ­upational Pois­oning in the Viscose Rayon Industry 1940. What an amazing career.

Finally she retired to write her autobiog­raphy, Expl­oring the Dangerous Trad­es (1943). Hamilton celebrated her 100th birthday in 1970, then passed away. Congress immediately passed the Occupational Safety and Health Act.

Did this talented woman ever marry? I wouldn't like to live to 100, all by myself. And I wouldn't like to be often moving between New York, Chicago, Boston and other cities all alone.

in my opinion, she didn't marry because she had to choose between her career and her personal life. However she was very lucky in one sense in that during her 22 years of residency at Hull House in Chicago, she was surrounded by excellent colleagues.

She, and many others like her, are the true celebrities of our lives, not the often vacuous 'entertainers' who make obscene amounts of money.

I know Alice Hamilton wasn't even nominated for a Nobel Prize, proving that women need to sing well and have naked boobs to be famous. And rich.

Dear Helen! Thank you telling about famous Dr. Alice Hamilton .

I hope Harvard's School of Industrial Medicine is named in Dr Hamilton's honour. She was dedicated and brilliant!

Andrew said...

One of many underappreciated and amazing women. What a different country the US was then, moving forward at a rapid pace in medicine, research and improvements for workers. Now, maybe not so much.

Dr Hamilton was very successful with the universities, hospitals and science labs. Even a lot of politicians wanted to look after their communities.

But I don't think the factory owners wanted to let her in, to inspect their machinery, chemicals and sewers. Even inside the factories, owners hid evidence of the dangers to workers' health. I presume the owners feared increasing costs and decreasing profits.

Paving the way for every other female doctor, thank you.

What a remarkable women who deserves far more recognition than she ever received. Her research must have gone a long way in making the work place a safer place.

Margaret D said...

What a brilliant woman she was, Hels. Very interesting read.

The impact of lead, mercury and zinc in particular MUST have been suspected before. But Dr Hamilton showed that female doctors could be very well educated, persistent in their research and dedicated to workers' health. She and her colleagues saved lives!

Her results were formally reported to the relevant Health authorities, of course. But she also reviewed each project in academic journals, spreading her reputation in the U.S and aboard.

Margaret
She was tireless!

Back in the day, I presented my research findings to experienced professionals at regular meetings, and to annual national conferences. I am glad I did it, but it was exhausting.

You find the most interesting people.

Sometimes I have lectured or written about special people and remember their details well eg Leonard Cohen. But the author of this post, Dr Joe, suggested Dr Hamilton.

Luiz Gomes said...

Obrigado por sempre nos surpreendem. Obrigado por cada aula de história. Que tenhamos mais mulheres assim.

Luiz
may we have many more women like Dr Alice Hamilton, and her team :)

I'm surprised I never heard of DR. Hamilton in my microbiological studies. Wow, what a lady. I've added that book to my reading list because she sounds like she had a fascinating life. And she gave back a lot to society too. :)

I think if Dr Hamilton had been a male, and if she had won a Nobel Prize for Medicine, you most certainly would have heard her name. After you read the book, drop a line here, if you would.
