The reclusive business icon was awarded with the Padma Bhushan, India’s third highest civilian award, in 2016. He joined the family business in 1947 as an 18-year-old and took over as chairman following his father’s demise.

The Tata Group stake had been passed down from his father Shapoorji Mistry, who picked up a stake in the 1930s, and Pallonji had very good relations with Ratan Tata and was well regarded in Bombay House, the Tata Group headquarters.

He is survived by four children, including Cyrus Mistry, who succeeded Ratan Tata as Chairman of the Tata Group in 2012 before being ousted unceremoniously in 2016. His daughter Aloo is the wife of Noel Tata, Ratan Tata’s step-brother.
