Recognising the contributions of engineers to the wheels of progress and technological development, India is celebrating Engineer’s Day on Friday, September 15, 2017. The date has been marked as a tribute to the of eminent Indian engineer Mokshagundam Visvesvaraya, who is known for the idea of dams with floodgates for which he was knighted by King George V and was later a recipient of the Bharat Ratna.

We learn about Visvesvaraya and his life on Engineer’s Day, but do we know about others who contributed to the field? Here are some personalities who made their mark in the pages of national engineering history:
