September 5 is celebrated as Teacher’s Day across India. This day also marks the birth anniversary of Dr Sarvepalli Radhakrishnan, who was a great philosopher and esteemed educationist. He was also the first Vice-President of India and the second President of India. But did you know, when he became the President of India, he used to accept only Rs 2,500 out of Rs 10,000 salary. The remaining amount was donated to the Prime Minister’s National Relief Fund every month.
