"Tributes to Bharat Ratna M. Visvesvaraya on his birth anniversary. An exemplary engineer himself, he is a source of immense inspiration," Modi tweeted.
"I salute all engineers on Engineers Day and appreciate their paramount role in the development of our nation," he said.
Visvesvaraya was the Diwan of Mysore from 1912 to 1918. He was given Bharat Ratna, India's highest civilian honour, in 1955.
