Forty years ago, grassroots Argentinian activists and scientists worked together to locate victims of unlawful killings and disappearances during Argentina’s “dirty war.” Three participants in that effort–Estela Barnes de Carlotto (president of Argentina’s Grandmothers of Plaza de Mayo), Morris Tidball-Binz (UN Special Rapporteur in residence at the Pozen Center), and Mimi Doretti (executive director of the Argentine Forensic Anthropology Team) – will look back on the pioneering forensic methods they developed, which are used today to investigate crimes against humanity worldwide. They will be joined by Anjli Parrin, Director of the Law School’s Global Human Rights Clinic, and Claudia Poblete, who was kidnapped as a child and reunited with her family thanks to the efforts of the grandmothers.
