"I am saddened to learn of Jim Tyree's passing. Jim was well known as both a business leader and a civic-minded Chicagoan who always gave back to the community. His service as Board Chairman of City Colleges, his work with non-profit organizations like the Juvenile Diabetes Research Foundation, and his investment in the Sun-Times made him a pillar of our city's civic life. He and I worked together on many important initiatives like combating diabetes and supporting stem cell research. He will be missed. Amy and my thoughts and prayers are with his family during this difficult time."
