Under Eliot, Harvard became a worldwide university, accepting its students around America using standardized entrance examinations and hiring well-known scholars from home and abroad. Eliot was an administrative reformer, reorganizing the university's faculty into schools and departments and replacing recitations with lectures and seminars. During his forty-year presidency, the university vastly expanded its facilities, with laboratories, libraries, classrooms, and athletic facilities replacing simple colonial structures. Eliot attracted the support of major donors from among the nation's growing plutocracy, making it the wealthiest private university in the world.
