John Canning: Chicago has felt the impact of Ken Griffin’s charity. Now we’ll feel the impact of his exit. – Chicago Tribune*

John Canning, founder and chairman of Madison Dearborn Partners: All told, Griffin has donated roughly $1.5 billion over the years to a variety of institutions and causes, giving well over a third of that total — over $600 million — right here in Chicago. Suffice to say, Citadel’s move will be another big setback for Chicago. Beyond the loss of good, high-paying jobs, significant tax revenue and the broad economic impact of the company, there is not another person who has had as large an impact on the city’s cultural and civic vitality — and on Chicagoans’ quality of life — as Griffin over the last 30 years.
