Harvard president Charles W. Eliot leads a movement for developing elective courses in college. Harvard requires a minimum of French or German, English composition and some work in physics and chemistry but allows students the freedom to select all other courses. Although at the time, many educational leaders oppose the elective system, leading universities and higher education innovators gradually will adopt the system. As a result, universities will add additional subjects to their curricula, such as history, sociology, psychology and economics.
