Look at Dr SP Mukherjee, the top rightwing leader at that time.
He was most celebrated educationist, was VC of best university of Asia- the calcutta university- for over a decade. And contributed immensely to education, nation building.
Or look at Sardar/Rajaji- congress leaders- but modern in outlook.
SO WHAT NEHRU DID BY ESTABLISING IITs etc WAS NOT UNIQUE. LOTS OF LEADERS HAD THAT CAPABILITY TO DO THE SAME.
