PATH also assisted developing countries in the production of their own health technologies. In 1995, Perkin was approached by Bill Gates Sr., who was seeking advice and information on family planning issues for his son's new philanthropic outlet, the Gates Foundation. Perkin offered his thoughts but also told the Gateses about the growing crisis in childhood immunizations. He didn't ask Gates for money or for a job. But his quiet competence got him both.
PATH is now one of the key players in the world health community.
And Perkin, at 65, is embarking on a new career as director of Gates' worldwide health initiative. Relive the highlights of their journey through words, photos and audio.
