Pathfinder International, based in Watertown, Massachusetts, is a global non-profit organization (NGO 501(c)(3)) that focuses on reproductive health, family planning, HIV/AIDS prevention and care, and maternal health. The organization operates in more than 20 developing countries throughout Africa, Asia, the Near East, and Latin America. According to their website, "Pathfinder International places reproductive health services at the center of all that we do—believing that health care is not only a fundamental human right but is critical for expanding opportunities for women, families, communities, and nations, while paving the way for transformations in development." While Pathfinder International was originally incorporated as The Pathfinder Fund in 1957, their family planning work began in the late 1920s when Pathfinder founder, Clarence Gamble, heir of the Procter & Gamble soap company fortune, supported efforts to introduce contraception to women and couples in the United States and 60 other countries. He also launched the first community-based service model, which is still the foundation of Pathfinder’s success today. Sarah Gamble, Clarence Gambles wife, named the organization in honor of a quote by the poet Antonio Machado, "Traveler, there is no path, paths are made by walking."
