David Servan-Schreiber died yesterday in France. A brain tumor survivor, Servan-Schreiber was a physician, a health advocate and the best-selling author of Anti-Cancer. He was also the moving force behind an "Appeal" for precaution in the use of mobile phones, issued in France in June 2008. The following month, Ron Herberman, then at the University of Pittsburgh Cancer Institute, issued a similar advisory. While Herberman's call for caution gained national attention, it was later repudiated by the Pittsburgh institute.
