J. William Diederich and his wife Mary have been the largest private benefactors in Marquette history.
Bill Diederich passed away on Monday, March 27, in Charlottesville, Va. He was 76.
The Marquette community mourns his death.
“Bill Diederich accomplished great things in life—in business, with his family and through his philanthropy,” said President Robert Wild, S.J. “His legacy will live here forever at Marquette University.”
Bill had learned of his Marquette University Alumnus of the Year Award for 2007 before his death.
In 2005, the Diederichs made a $28 million gift to Marquette establishing the J. William and Mary Diederich College of Communication.
Bill made the gift because he wants Marquette to be an incubator for the next generation of ideas in the fields of communication, educating students to be leaders in the converging world of print, broadcast and electronic communication.

His contribution will continue long into the future in our college and university. He will be remembered and missed.
