William C. Powers Jr., a long-serving president of the University of Texas who earlier produced a scathing report in 2002 on the wrongdoing that led to the collapse of the Enron Corporation, died on Sunday in Austin. He was 72.

His family said the cause was complications of a fall and of oculopharyngeal muscular dystrophy, a rare, adult-onset muscle disorder.

Mr. Powers was president of the University of Texas at Austin, the flagship campus of the state’s sprawling university system, from 2006 to 2015.

But it was while he was a top legal scholar and dean of the University of Texas law school that he came to national prominence. In 2001 he joined Enron’s board and agreed to lead a committee to investigate the company’s financial dealings. Its findings led to one of the nation’s largest corporate scandals and the collapse of Enron, a Houston-based energy company that had started to implode in 2000.
