Washington University Chancellor Mark Wrighton is planning to retire after two decades leading the school.

Wrighton told Washington University’s board of trustees of his decision to step down on Friday, the 22nd anniversary of being inaugurated chancellor. He was hired in 1995.

Ask Washington University Chancellor Mark Wrighton why the school is embarking on a year-long effort to determine causes and solutions to gun violence, and he has a host of statistics and academic rationales to make his case:

  • The cost to the nation of $174 billion each year.
  • More than 11,000 U.S. homicides and nearly twice that number of suicides from firearms in 2013.
  • Missouri’s ranking of fourth in the nation for killings with guns.

But Wrighton's wife, Risa Zwerling Wrighton, has a far more emotional argument, one that moves her to tears.

This article first appeared in the St. Louis Beacon: President Bill Clinton is no stranger to Washington University.

The private university was home to the first presidential debate in 1992, when the then-Arkansas governor squared off in a rhetorical showdown with incumbent President George H.W. Bush and Texas businessman Ross Perot. Less than a month later, Clinton would defeat both men to become the nation’s 42nd president.
