K. Kamaraj (1903-1975) was a prominent freedom fighter and served as the President of the Indian National Congress. He held the position of Chief Minister in Madras (now Tamil Nadu). Despite facing educational challenges in his own life, he dedicated himself to the cause of education by working to expand its reach in the Madras province.

In 1963, he put forth the influential 'Kamaraj Plan', which advocated for the voluntary resignation of senior Congress leaders to create opportunities for younger members within the party.
