The President of the University of Michigan is the principal executive officer of the University of Michigan. The office was created by the Michigan Constitution of 1850, which also specified that the president was to be appointed by the Regents of the University of Michigan and preside at their meetings, but without a vote. Between the establishment of the University of Michigan in 1837 and 1850, the Board of Regents ran the university directly; although they were, by law, supposed to appoint a Chancellor to administer the university, they never did, and instead a rotating roster of professors carried out the day-to-day administration duties.
