Linda Rae Murray, MD, MPH, a champion of social justice and outspoken advocate for the medically underserved for more than 40 years, is not easy to describe. Part E. F. Hutton (when she talks, people listen), part streetwise negotiator (she's not shy about dropping a four-letter word into conversation), she might come across as brash and intimidating to some. But those who know her well will attest to her softhearted interior, and her unwavering commitment to speaking out in the name of better health for all.
