He is survived by his wife, Susan Wollenberg; two daughters, Anna and Ruth, and their mother, Patricia Washington; two sons, Richard and James; and six grandchildren.
“He was a gifted man with a deep understanding of the importance of the arts and the importance and value of education for all Americans,” the family wrote.
“The many times he visited his home state he was a beloved member of the people of Wisconsin.”
