Farmer's son, who hails from village in Bihar in eastern India, Samprada Singh worked at a chemist's store before venturing out on own distributing pharmaceuticals. He later got into manufacturing in Mumbai with a friend. But that unraveled, and he broke away to set up Alkem Laboratories in 1973. Today it is one of the nation's top 10 generic firms, known for such brands as Clavam and Taxim, both antibiotics. Singh says he wants to more than double Alkem's revenues to $1 billion by 2016, by expanding into overseas markets. Younger cousin Basudeo Narain Singh, who shares the fortune, helps him run company. Alkem's offices are decorated with photos of Singh with the quote "Yet miles to go. Yet a lot to be done."
