Engineer’s Day is observed in India every September 15 to honor Sir Mokshagundam Visvesvaraya, a distinguished engineer, scholar, and statesman, who was born on this date in 1860. The day commemorates his significant contributions to engineering, particularly in dam and irrigation systems. Visvesvaraya gained recognition for his innovative flood protection system for Hyderabad and his work on protecting Visakhapatnam port from sea erosion. He was awarded the Order of the Indian Empire and Bharat Ratna for his achievements and held several doctoral degrees from various universities in India. Celebrations typically involve recognizing the contributions of engineers to society and promoting the engineering profession. Engineer’s Day serves as a reminder of the importance of engineering in national development and infrastructure.
