Ganga N. Ghosh is an 89-year-old mechanical engineer. He has solved many vexing problems for multinationals. Yet at an early age of 49, he wrapped up his engineering business, in 1978, so he could dedicate his life towards improving public sanitation—specifically garbage, toilet, and air pollution. He trotted the globe to observe waste-management techniques and concrete structural details in all the continents. Although he lives in America with his family, his heart remains in India.
