How do you go from being a shopkeeper to multi-billionaire in 40 years?

He is low-profile, eschews media, and continues to operate from a small office in Delhi. In this candid and captivating biography Kuldip reveals his story for the first time.

Kuldip lost his father to an accident early in his life. He and his brothers, Sohan and Gurbachan, started as shopkeepers in Amritsar. From an annual turnover of Rs. 10 lakh in 1970, the Dhingras have built a business with an annual turnover of over Rs. 7,500 crore today. They are among the top 30 richest families in India with a net worth of over $4.5 billion.

This never-before-told story of Kuldip moves from Amritsar to Europe to Delhi where he became the largest exporter to the Soviet Union in the 1980s. In 1990 the Dhingras bought Berger.
