The Tata success story begins when Jamshedji Tata (1839-1904) set up a company to mine coal and iron ore in Bihar. In the years to come, it became India's largest steel production centre, the city that grew around it renamed Jamshedpur. The real diversification and spectacular upsurge in Tatas' fortunes came during JRD's 52-year tenure at the helm of its affairs. He took over as chairman at the age of 34 and guided its course till he died in 1993.
