Nand Lal Gupta
This wonderful 85-year old man has been helping the remotest villages in Himachal Pradesh through his inventions for over 50 years now. A self-trained scientist, Gupta’s high-tech innovations in the field of adhesives, pine boards as wooden board substitutes and soil bricks have awed scientists working in various reputed institutions across the country. His methodology to make pine boards and pine wool by utilizing pine needles available in the forests has opened many livelihood options for the people in the villages. He has managed to make six different types of adhesives from cactus. Age is not a concern for this energetic man as he plans to invent many more such tools that could simplify the lives of people living in the Himalayas.
