CHICAGO–(BUSINESS WIRE)–Madison Dearborn Partners, LLC (“MDP”), a leading private equity firm based in Chicago, announced today that it has engaged industry leader John Lewis as an Executive Partner in pursuit of attractive investment opportunities for MDP’s funds across the information services landscape. In particular, Mr. Lewis, who most recently served as Global President of Nielsen Holdings PLC (NYSE:NLSN), will assist MDP in identifying and developing businesses with differentiated capabilities in data and business analytics.
