Arunachalam Muruganantham is a social entrepreneur from Coimbatore in Tamil Nadu, India. He invented a low-cost sanitary pad-making machine and has innovated grass-roots mechanisms for generating awareness about traditional unhygienic practices around menstruation in rural India. His motivation for inventing the machine was to help poor women live with dignity. His mini-machines, which can manufacture sanitary pads for less than a third of the cost of commercial pads, have been installed in 23 of the 29 states of India and have created livelihoods for thousands of women. He is currently planning to expand the production of these machines to 106 nations. In 2014, TIME magazine placed him in its list of 100 Most Influential People in the World.
