Gary Null (1945– ) is one of the nation's leading promoters of dubious treatment for serious disease. He hosts radio and television talk shows; writes books and magazine articles; delivers lectures; and markets products through his Web site. According to an article in East West magazine, Null became interested in nutrition during his twenties while working as a short order cook in New York City, where he now resides. He researched the subject and wrote The Complete Guide to Health and Nutrition, which was published in 1972 and sold briskly after Null appeared on a succession of prominent talk shows. He began hosting radio shows around that time and eventually got his own show on WABC, the flagship radio station of the ABC network. Later he moved to WMCA, which broadcast Null's show on Sunday nights to many stations across the United States. For many years, he also hosted a daily show on WBAI and a Sunday evening program on WEVD in New York City. I have been tracking his activities since the mid-1970s.
