How a non-physician schoolteacher redesigned the entire American medical education system in 1910.

In short: In 1910, the Flexner Report fundamentally altered American medicine by mandating a rigid, science-based biomedical model. While it elevated standards and research, it also triggered the mass closure of medical schools, marginalized alternative practices, and introduced systemic barriers that disproportionately impacted women and African American students for generations.

The transformation of American medical education was driven by the Hopkins Circle, a group of influential figures including William Welch, William Osler, and Frederick Gates. Gates, a trusted adviser to John D. Rockefeller, was galvanized to reform medical training after reading Osler’s Textbook of Medicine. He secured Rockefeller’s philanthropic resources to support the project, which was executed by Abraham Flexner, an educator and former private school owner who had no formal medical training.

Flexner’s 1910 report, published by the Carnegie Foundation, surveyed all 155 medical schools then operating in North America. He advocated for a model inspired by German university medical schools, emphasizing laboratory-based science and clinical training. The report was scathing toward institutions that failed to meet these new standards, famously labeling Chicago’s medical schools a national disgrace. Consequently, nearly half of all American medical schools closed or merged in the years following the report’s publication.

The report’s impact extended far beyond curriculum reform. By establishing the biomedical model as the gold standard, it effectively delegitimized alternative medical traditions such as homeopathy, electrotherapy, and botanical therapies. Furthermore, the push for centralization and higher admission standards led to the closure of most medical schools serving African Americans and pushed universities toward male-only enrollment. While the United States subsequently became a global leader in medical research, these changes created lasting inequities and a persistent imbalance between the scientific and humanistic aspects of medical practice.
