The Rev. Patrick Dillon served as the second president of the University of Notre Dame from 1865 to 1866. He succeeded Fr. Edward Sorin when Sorin decided to focus on his job as Provincial of the Congregation. His brief tenure featured the construction of the second main building.[1] Dillon instituted the Commercial Course, which offered students the opportunity to study bookkeeping andcommercial law. He also laid the foundations for the development of a course in the sciences.[2] He was popular with students because of his disciplinary leniency.[3]
