Christopher C. Langdell (1826-1906) is one of the most influential figures in the history of American professional education. As dean of Harvard Law School from 1870 to 1895, he conceived, designed, and built the educational model that leading professional schools in virtually all fields subsequently emulated. In this first full-length biography of the educator and jurist, Bruce Kimball explores Langdell's controversial role in modern professional education and in jurisprudence.Langdell founded his model on the idea of academic meritocracy. According to this principle, scholastic achievement should determine one's merit in professional life. Despite fierce opposition from students, faculty, alumni, and legal professionals, he designed and instituted a formal system of innovative policies based on meritocracy. This system's components included the admission requirement of a bachelor's degree, the sequenced curriculum and its extension to three years, the hurdle of annual examinations for continuation and graduation, the independent career track for professional faculty, the transformation of the professional library into a scholarly resource, the inductive pedagogy of teaching from cases, the organization of alumni to support the school, and a new, highly successful financial strategy.Langdell's model was subsequently adopted by leading law schools, medical schools, business schools, and the schools of other professions. By the time of his retirement as dean of Harvard Law School, Langdell had instituted the future model for professional education throughout the United States.
