PSR has a long and rich tradition.  In 1961, taking the name Physicians for Social Responsibility, a small group of university-based physicians concluded, "… in the aftermath of a nuclear war, no meaningful medical response would be possible. The only cure is prevention."  The aggressive and effective thrust to educate the medical community and the general public to take a stand against nuclear weapons, was acknowledged in 1985 when the Nobel Peace Prize was awarded to PSR as an affiliate of International Physicians for the Prevention of Nuclear War (IPPNW).
The Philadelphia chapter of PSR was formed in 1970 to support the national initiative to prevent nuclear war. In the early 1990's, the membership voted to shift its primary focus from nuclear disarmament to interpersonal violence prevention, working through educational initiatives, coalition building and collaborative advocacy.  Current programs focus on illuminating and addressing the root causes of interpersonal violence;  healing children who have been the victims of, or have witnessed, interpersonal violence; teaching school children that there are alternatives to violent behavior; inspiring healthcare and other interested professionals to identify the causes of violence and work to promote healing and prevention; and providing a forum for clinicians and medical students to focus on the delivery of compassionate and quality care giving.
