According to family sources, the end came late Sunday at his residence in the southern suburb of the city. He leaves behind his wife, son, daughter and two grand children. As the architect of the nationwide computer network (NICNET), Seshagiri drafted the software and hardware policies that revolutionised information technology (IT) in the country.

"Seshagiri was instrumental in the setting up of the software technology parks of India, which led to the emergence of Indian IT bellwethers such as Infosys and Wipro in Bangalore and TCS in Bombay (Mumbai) three decades ago," city-based NIC director A. Venkateshan told IANS late Tuesday. Recipient of several awards, including Padma Bhushan in 2005 and Karnataka Rajyotsava, Seshagiri strived hard to get the US-based global chip maker Texas Instruments to open its offshore development centre in Bangalore, with his 'flood-in and flood-out software policy'.
