Ratan Tata, former chairman of Tata Group, passed away on October 9. The 86-year-old industrialist was in a critical condition and was admitted to the Breach Candy Hospital in Mumbai on Monday. The Padma Vibhushan awardee was best known for his ability to turn vision into reality. He has left a legacy that goes far beyond his businesses. Perhaps the example that speaks volumes about his economic understanding of Indian society is the Tata Nano car.
