The 2013 Hillman Prize for Magazine Journalism goes to an outstanding investigative team from the Chicago Tribune for “Playing With Fire,” an expose of the machinations of the chemical industry and Big Tobacco to put ineffective and potentially hazardous flame-retardant chemicals in mattresses, couch cushions, and other soft furnishings. The dogged reporting of Patricia Callahan, Sam Roe, and Michael Hawthorne revealed falsified fire tests, a successful bid to infiltrate the ranks of state fire marshalls, and much more.
