Episode notes

Today, becoming a doctor means years of formal education, licensing examinations, clinical rotations, and residency training. In colonial America, the process could be considerably simpler: find a physician willing to take you as an apprentice, read his books, accompany him on patient visits, and eventually receive his blessing to practice medicine yourself.

There was no standardized curriculum, no uniform examination, and little guarantee that one physician’s training looked anything like another’s.

Over the nineteenth century, that system began to change. Medical schools proliferated, apprenticeship gradually declined, ambitious Americans traveled to Paris and Germany for better training, laboratory science transformed the understanding of disease, and universities began building a new kind of medical education around science, research, hospitals, and direct experience with patients.

In this episode of Beyond Ether Dome, we examine the origins of American medical education and how the United States began the long transformation from apprenticeship to the modern medical school.

We discuss:

• How physicians were trained through apprenticeship in colonial and early America
• What a good apprenticeship might provide, and how spectacularly bad an unregulated one could be
• The first American medical schools and why they initially supplemented rather than replaced apprenticeship
• The rise of proprietary, physician-owned medical schools in the nineteenth century
• Why for-profit medical education expanded so rapidly
• The remarkably limited requirements for earning an early American medical degree
• How financial incentives could conflict with educational standards
• Why ambitious American physicians traveled to Paris for medical training
• The Paris school’s emphasis on bedside observation, physical examination, autopsy, and pathological anatomy
• Pierre Charles Alexandre Louis and the “numerical method” for evaluating treatments such as bloodletting
• Why Germany replaced Paris as the leading destination for American physicians after the Civil War
• The German model of university-based medicine, laboratory science, research, and teaching hospitals
• How scientific discoveries in physiology, pathology, microscopy, and bacteriology changed what physicians needed to know
• William Osler, William Stewart Halsted, and the European influences that helped reshape American medical training
• The rise of the American research university after the Civil War
• Early reforms at Harvard, Michigan, and Pennsylvania
• The opening of Johns Hopkins School of Medicine in 1893 and the emergence of a recognizably modern medical curriculum
• Clinical clerkships, residency training, research, and the growing importance of the teaching hospital
• Mary Garrett and the admission of women to Johns Hopkins
• Why American medical education entered the twentieth century with radically different kinds of schools granting essentially the same medical degree

By 1900, the United States had developed many of the essential ingredients of modern medical education. The problem was that they were anything but universal.

Elite university medical schools were embracing laboratory science, research, rigorous admissions, clinical clerkships, and teaching hospitals. At the same time, weaker proprietary schools continued operating under educational standards that could differ enormously from one institution to another.

Part 1 ends with American medicine confronting that contradiction. Part 2 asks how reformers tried to solve it, and what America gained and lost when they did.

In the early 1930s, thousands of men went into Gauley Mountain in West Virginia to build a hydroelectric tunnel for Union Carbide. Inside, they drilled and blasted rock containing extraordinarily high concentrations of silica. The dust was sometimes so thick workers said they could barely see one another.

Then the men began to die.

Many were Black migrant laborers from the South. Some became desperately ill after only months, or even weeks, underground. Yet company physicians minimized their illness, sometimes calling it “tunnelitis” or attributing deaths to pneumonia and tuberculosis. Other doctors used X-rays, autopsies, and medical testimony to show what was really happening: devastating occupational silicosis.

In this episode of Beyond Ether Dome, Robert and Bart examine the Hawk’s Nest Tunnel disaster, often described as one of the deadliest industrial disasters in American history.

We discuss:

• Why Union Carbide wanted a tunnel through Gauley Mountain
• Dry drilling, silica dust, poor ventilation, and the conditions inside the tunnel
• Why silicosis was already a known and preventable occupational disease
• How inhaled crystalline silica causes progressive pulmonary fibrosis
• The close relationship between silicosis and tuberculosis
• The Jones family, who lost three sons after they worked in the tunnel
• Company physicians, “tunnelitis,” and the consequences of controlling a diagnosis
• Dr. Leroy Harless and the physicians who helped document the disease
• Silicosis expert Anthony Lanza and the role of respected medical authority in minimizing the disaster
• Lawsuits, settlements, and compensation laws that often failed the very workers they were supposed to protect
• The role of race in working conditions, compensation, record-keeping, and historical memory
• Philippa Allen, labor journalists, and the campaign that finally brought Hawk’s Nest before Congress
• The 1936 congressional investigation
• Why the true death toll remains uncertain, with later scholarship estimating at least 764 deaths
• Union Carbide’s efforts to dispute the scale and cause of the disaster
• The long legacy of Hawk’s Nest in occupational medicine and workplace safety

Hawk’s Nest was not a mystery disease, and it was not an unavoidable accident. The danger of silica was known, methods of controlling dust already existed, and the deaths were preventable.

The tragedy was not that medicine lacked the knowledge to protect these workers. It was that knowledge proved remarkably easy to ignore when recognizing the disease carried an economic cost.

The Black Death never really disappeared.

In this episode of Beyond Ether Dome, Dr. Lane and Dr. Patenaude follow plague from the great pandemics of the ancient and medieval world to the American West, where Yersinia pestis still survives in wild rodent populations today.

Topics include:

• The Plague of Justinian and the medieval Black Death
• How ancient DNA finally proved that Yersinia pestis caused the Black Death
• The 2022 Nature study tracing its origins to Central Asia
• Alexandre Yersin and the discovery of the plague bacillus
• British investigations of rats and fleas during the Third Pandemic
• The arrival of plague in San Francisco in 1900
• Joseph Kinyoun, Chinatown quarantines, racism, and political denial
• Rupert Blue and the campaign to control rats and rebuild San Francisco
• The 1906 earthquake and the second San Francisco outbreak
• The discovery of plague in California ground squirrels
• The spread of plague into prairie dogs and other western wildlife
• The ecological consequences for the endangered black-footed ferret
• How cloning is now being used to restore genetic diversity to the species

From medieval graveyards and early bacteriology to San Francisco, prairie dog towns, and modern conservation genetics, this episode traces the remarkable journey of a disease that helped reshape human history and then became permanently established in the American West.
