COLUMBIA, Mo. — One of the University of Missouri’s first black law school graduates was appointed Thursday to lead the four-campus system through a tumultuous period of racial unrest, drawing praise from students who said he’s well-equipped to confront the problems they felt his predecessor largely ignored.

Michael Middleton, 68, has spent 30 years at the university — as an undergraduate, law student, faculty member and finally, administrator. At a news conference announcing his appointment as the university system’s interim president, he vowed to take on the racial problems that inspired the protests that helped force Monday’s abrupt resignation of President Tim Wolfe and another top administrator.

Middleton said the university “has faced its share of troubling incidents and we recognize that we must move forward as a community. We must embrace these issues as they come, and they will come to define us in the future.”
