The Harvard case method conquered American law teaching nationwide by 1903.

Evidence

The Langdell method had, as we saw, struggled to stay alive even in its mother church in Cambridge during its early years. By 1900, it was clearly on the move and conquering new territory. Criticism of the Harvard method continued; it was inefficient, it was elitist, it did not fill the needs of the students in night law schools—​or in day law schools for that matter—​but this was, as it turned out, a losing battle. The armies of Langdell eventually swept the field, spreading the gospel of casebooks and Socratic dialogue throughout the country. Yale was a convert in 1903. — Lawrence M.
