The document summarizes the story of A Muruganantham, a school dropout from rural India who designed an inexpensive machine to produce sanitary napkins in order to make menstrual hygiene more affordable and accessible for women in rural areas. His machine is now installed in 250 locations across 18 Indian states. He does not view his work as a business but rather as a social cause, and has received national recognition for his innovation including the National Innovation Foundation's grassroots innovation award.
