Satish Dhawan, the 3rd chairman of ISRO after whom the Sriharikota space center is named, and the man who shaped the organization and it's process to what it is today.
Thread on his Jayanti today.

While Vikram Sarabhai, is well known as the founder of ISRO, it was Satish Dhawan who actually built on that foundation, put down the processes and structure that would define it and was a major reason for it's success.

The father of experimental fluid dynamics research in India, one of the eminent researchers in the field of turbulence, was born on September 25, 1920 in Srinagar, and graduated from Lahore University with a rather unusual combination-BA (Maths), BE(Mech) and ME( Engg Litt).

When India became independent in 1947, Satish Dhawan, let for US to do his higher studies where he graduated in MS(Aerospace Engineering) from University of Minnesota and a Masters in Aeronautical Engineering from Cal-Tech and a double PhD in maths and aerospace engineering.

It was during his time, that the department emerged as center of experimental fluid dynamic research in India. In fact it was a pilot project conducted by him that resulted in setting up the world class wind tunnels for aerodynamic testing at the National Aerospace Lab( NAL).
