Sidney M. Wolfe, M.D. founded the Health Research Group in 1971 with Ralph Nader, part of the enterprise that launched as Public Citizen that same year. Sid invented a new approach of "research-based advocacy" to get dangerous drugs and devices off the market, win new protections for worker health and safety, address doctor misconduct, challenge the Food and Drug Administration (FDA) to do its job, and hold pharmaceutical companies accountable.
