In 1996, following a cover story he wrote in "The New York Times Magazine" about global land-mine proliferation, he co-founded Physicians Against Landmines/Center for International Rehabilitation (CIR). An international, non-governmental humanitarian organization, CIR sponsors field hospitals, wheelchair and prosthetics programs, plus prosthetics-fabrication training and disability advocacy in post-conflict nations worldwide. In 1997, as an early member of the International Campaign to Ban Landmines, CIR was a co-recipient of the Nobel Peace Prize. In 2006, working with the United Nations Special Rapporteur for Disabilities, CIR was central to the UN’s Convention on the Rights of Persons with Disabilities, the most-rapidly ratified UN Convention to ever gain approval by the UN General Assembly. Webster served as CIR's vice-chairman.
