Arunachalam Muruganantham

In 2014, he was included in Time magazine's list of 100 Most Influential People in the World. In 2016, he was awarded the Padma Shri by the Government of India.

Muruganantham has become well-known as a social entrepreneur. He has given lectures at many institutions including IIT Bombay,, IIT Madras, IIM Ahmedabad, IIM Bangalore, Birla Institute of Technology and Science, Pilani – Goa Campus and Harvard University. He has also given a TED talk. His story was the subject of a prize-winning documentary by Amit Virmani, Menstrual Man, and the film Phullu (2017) directed by Abhishek Saxena. Director R. Balki cast Indian actor Akshay Kumar as Laxmikant Chauhan in a film based on Muruganantham's life, titled Pad Man.

In 2006, he visited IIT Madras to show his idea and receive suggestions. They registered his invention for the National Innovation Foundation's Grassroots Technological Innovations Award; it won the award. He obtained seed funding and founded Jayaashree Industries, which now markets these machines to rural women across India. The machine has been praised for its simplicity and cost-effectiveness, and his commitment to social aid has earned him several awards. Despite offers from several corporate entities to commercialize his venture, he has refused, and continues to provide these machines to self-help groups (SHGs) run by women.

In 1998, he married Shanthi. Shortly after, Muruganantham discovered his wife collecting filthy rags and newspapers to use during her menstrual cycle, as sanitary napkins made by multinational corporations were expensive. Troubled by this, he started designing experimental pads. Initially, he made pads out of cotton, but these were rejected by his wife and sisters. Eventually, they stopped co-operating with him and refused to be the test subjects for his innovations. He realised that the raw materials cost ₹ 10 (14¢ US), but the end product sold for 40 times that price. He looked for female volunteers who could test his inventions, but most were too shy to discuss their menstrual issues with him. He started testing it on himself, using a bladder with animal blood, but became the subject of ridicule when the "sanitary pad" was discovered in his village. As menstruation was a taboo subject in India, it left him ostracized by his community and family. He distributed his products free to girls in a local medical college, hoping that they would give him feedback.
