"Our hearts are very heavy today. Our dad was a passionate businessman committed to making Chicago a great place to live, work and visit, but his true love was for his family and close friends," Wirtz son, Blackhawks CEO Danny, said. He was a loving father, a devoted husband to Marilyn, a brother, a nephew, an uncle and a doting grandfather to his six remarkable grandchildren. His passing leaves a huge hole in the hearts of many and we will miss him terribly."
