In 1910, the man who rewrote American medicine had no medical degree. He ran a prep school.
Abraham Flexner visited all 155 American medical schools in 1908-1909 and wrote the report that shut down most of them. His qualifications: a bachelor's degree and experience running a private prep school in Louisville, Kentucky.
The report was funded by Rockefeller and Carnegie. By 1920, women had dropped from 50% to 4% of American doctors. Six Black medical schools closed.
Flexner never practiced medicine a day in his life.
