Pingali Venkayya (died 1963) was an Indian freedom fighter and the designer of the flag on which the Indian national flag was based. Various so-called national flags had been used by members of the Indian independence movement prior to independence being achieved in 1947. Venkayya’s version was first designed for the Indian National Congress and subsequently modified in 1947.
According to The Hindu, “Pingali Venkayya was an authority in geology, agriculture and also an educationist who set up an educational institution in Machilipatnam. He, however, died in poverty in 1963 and was largely forgotten by the society and by his own party, the Congress.” A postage stamp was issued to commemorate him in 2009 and in 2011 it was proposed that he be posthumously awarded the Bharat Ratna. The outcome of that proposal is not known.
