This book is dedicated to the memory of Jean Gabriel Fils, who died on May 28, 2006, at the age of 35, in Central Haiti, where he had lived all his life. Known widely and affectionately as “Ti Jean,” he had been our friend and colleague since Zanmi Lasante’s earliest days. As director of Zanmi Lasante’s Program on Social and Economic Rights, he laid the foundations for hundreds of new homes for patients and others living in destitution. He also used the struggle for AIDS treatment and health care as a national and international platform from which to call for social justice and human dignity for all. We hope to carry on the work on his behalf.
