Alice Hamilton, MD (1869-1970)

Many of the first laws and regulations passed to improve the health of workers were the direct result of the work of one dedicated and talented woman, Alice Hamilton, MD. Born into a prominent family in Indiana, Dr. Hamilton graduated from medical school at the University of Michigan in 1893. After accepting a teaching position at the Women’s Medical School of Northwestern University in 1897, she moved into Jane Addams’ Hull House in Chicago, where she lived with immigrants and the poor. As she provided medical care, she came to realize that jobs were a major source of injury and illness for workers and their families. For example, men who worked with asbestos or lead exposed their families through the work clothing they brought home to be washed. There she opened a well-baby clinic for poor families in the local settlement house neighborhood. As she acquainted herself with the families, she learned of their pains, strange deaths, lead palsy, “wrist drop,” and of the high numbers of widowed women. Encouraged by the reformers of Hull House, she began to apply her medical knowledge to these social problems and thus began her scientific inquiry into occupational health for which she became known.

Dr. Hamilton quickly realized that while some progress in understanding occupational illness and disease was being made in Europe, little was written or understood about occupational disease conditions in the U.S. In 1908, she published one of the first articles on occupational disease in this country and was soon a recognized expert on the topic. Starting in 1910, under the sponsorship initially of a commission of the State of Illinois, and later the Federal Bureau of Labor Statistics, she conducted a series of brilliant explorations of occupational toxic disorders. Relying primarily on “shoe leather epidemiology,” and the emerging laboratory science of toxicology, she pioneered occupational epidemiology and industrial hygiene in the U.S. Her findings were so scientifically persuasive that they caused sweeping reforms, both voluntary and regulatory, to improve the health of workers.


In 1919, Dr. Hamilton was appointed Assistant Professor of Industrial Medicine at Harvard Medical School and became the first female faculty member at Harvard University. There she served two terms on the Health Committee of the League of Nations. She moved to the Harvard School of Public Health upon its founding and chaired the Department of Industrial Medicine. While she was considered to be the best candidate for the position, the University was against the idea of a woman educating men, as the predominant idea at the time was that only men can educate men. But the School of Public Health’s leaders persisted, and eventually the University accepted her on their faculty in Industrial Medicine. The department would eventually give birth to the training program in Occupational and Industrial Medicine. When she retired from Harvard at the age of sixty-six, she became a consultant to the U.S. Division of Labor Standards and served as President of the National Consumers League.

Harriet Hardy photo

Harriet Hardy, MD (1906-1993)

Harriet L. Hardy (1906-1993) was a student of Dr. Alice Hamilton and a pioneer in the field of occupational medicine. She was also the first woman professor at Harvard Medical School. She attended Wellesley College and medical school at Cornell University and completed residency training at Philadelphia General Hospital. Her investigation into the respiratory illness among workers making fluorescent lamps at the General Electric and Sylvania plants on Boston’s north shore led to the revelation of the harmful effects of beryllium exposure, leading to precautions allowing safer use of beryllium. She also worked with the Atomic Energy Commission in Los Alamos, N.M. to study the hazards associated with nuclear energy. She was also among the first to link asbestos and cancer. She also held leadership roles at the Atomic Energy Commission, United Mine Workers, and the National Institute for Occupational Safety and Health (NIOSH).

M. Christine David, DO, MPH (OEMR Class of 2012)

M. Christine David, DO, MPH is a native New Yorker who majored in languages in New York University. She completed her medical training at the New York College of Osteopathic Medicine. After some training in family medicine, Christine pursued her passion for public health, completing Preventive Medicine Residency at University of Massachusetts Medical Center, where she also earned her Master’s in Public Health. Christine explored such avenues of interest as obesity, health disparities and maternal-child health issues – topics which served as the source of her preventive medicine research project. A clinical rotation in occupational medicine, however, proved to be a pivotal point in her career; it provided her with the ability to combine her two loves of preventive health practices with direct patient care. She continued her training at the Occupational and Environmental Medicine Residency of the Harvard School of Public Health (Class of 2012). During her time at HSPH, she developed an interest on workplace wellness and health promotion while researching methylmercury as an environmental reproductive hazard. Christine has worked in the urgent care setting and such occupational medicine practices as Concentra and Quadrant Health Strategies, all of which allowed her to deepen her clinical skills. As the medical director of the Working Well Clinic in Boston Medical center, she led the annual Flu vaccination and Tuberculosis Screening campaigns in addition to leading the clinical staff in providing quality clinical care to the 11,000 employees of the site.

What she likes about OEM: Dr. Langer was attracted to occupational medicine due to the variety of focus areas offered by this discipline, such as direct patient care, preventive medicine, health promotion and worker productivity, disability management, research, and education.  In reality, occupational medicine physicians have been practicing “population health” long before this term was coined.  She further appreciates the range of available work settings, including, but not limited to, clinical, administrative, academic, corporate, government, and military.

Rose Goldman photo

Rose Goldman, MD, MPH (OEMR Class of 1981)

Dr. Goldman is Associate Professor of Medicine at Harvard Medical School and Associate Professor of Environmental Health at the Harvard T.H. Chan School of Public Health. Her career started as a medical resident when did a rotation with the inspiring Dr. Irving Selikoff, who showed her a career path that could combine her interests in the environment with a passion to help workers. She then went to the newly created preventive medicine (occupational/environmental medicine) program at HSPH in 1979-1981. From there, she crafted a position that combined internal medicine and occupational & environmental medicine at Cambridge Hospital, while also serving part time as the occupational health physician for the Massachusetts Department of Labor’s Division of Occupational Health—following in the footsteps of Dr. Harriet Hardy who held that same position where she did her seminal beryllium research. Dr. Goldman started the occupational and environmental health program at Cambridge Hospital, and was the founding Chief of the Division of OEM at Cambridge Health Alliance (CHA). Early in her career she and other colleagues created a new model for delivering clinical occupational medicine: an academically affiliated occupational/environmental medicine clinic that serves the community: workers, companies, unions, and hospital/health centers. This model spread and lead to the creation of Association of Occupational and Environmental Clinics (AOEC). In 2010 she transitioned from CHA’s Chief of Occupational and Environmental Medicine to become the Department of Medicine’s Director of Faculty Affairs. In her career, she has combined clinical occupational and environmental medicine with public health, research, and education. Her clinical practice has a focus on environmental toxicology, particularly metals (lead) and she has authored numerous publications. She has brought attention to pediatric environmental health issues and has served as the Associate Director for the New England Pediatric Environmental Health Special Unit. As an ardent and experienced educator, she has held course leadership positions at Harvard’s Schools of Public Health and Medicine, and developed and implemented educational innovations involving participatory education methods.

What she likes about OEM: Dr. Goldman likes the opportunities for clinical assessment, particularly toxicological; preventive medicine interventions, teaching, research, and advocacy.
