The election of Rahm Emanuel as mayor of Chicago followed the retirement of Mayor Richard M. Daley; 2011 also saw the passing of Maggie Daley. Emanuel is close to several corporate executives and investment gurus who supported his campaign and also serve on a council to help spur economic development in the city. Leadership changes also shook up The Economic Club of Chicago, where Grace Barry departed as president and a replacement has yet to be named, and The Executives' Club of Chicago, where Melissa Bean took over as chief executive after years of leadership by Kaarina Koskenalusta.
