In more such outpourings, Tata Sons chairman N Chadrasekaran penned a heartfelt note for the man, who has left a legacy for others to follow in the coming decades.

In a post on LinkedIn, Chandrasekaran wrote, "Our relationship grew over the years, first focusing on business and eventually evolving into a more personal connection.

"We discussed interests ranging from cars to hotels, but when our conversations turned to other matters—those of daily life—he would show how much he noticed and felt. He was someone to be discovered, over time and through experience."

Recalling an incident of wage dispute between Tata Motors and its employees' union in 2017, Chandrasekaran said Tata was always focussed on taking care of employees' well being.

"Mr. Tata's direction squarely focused on making sure employees were well taken care of—not just to resolve the dispute, but to ensure their and their families' well-being. Across other Group companies, his perspective on employees was uniform.

"It is something that has shaped a number of our leaders across the Group," the chairman said.

Tata passed away at the age of 86 on Wednesday night at Mumbai's Breach Candy Hospital.

The former chairman of Tata Group and a national icon for his august bearing and exemplary business ethics was undergoing treatment at Mumbai's Breach Candy Hospital after his admission there during the day. Following his admission his condition worsened and turned critical.
