Why I Am an Atheist was written by the revolutionary who was executed at what age?
Bhagat Singh Bhagat Singh (] 1907  – 23 March 1931) was a charismatic Indian socialist revolutionary whose two acts of dramatic violence against the British in India and execution at age 23 made him a folk hero of the Indian independence movement.
Nathuram Godse Nathuram Vinayak Godse (19 May 1910 – 15 November 1949) was a right wing advocate of Hindu nationalism who assassinated Mahatma Gandhi, shooting him in the chest three times at point blank range in New Delhi on 30 January 1948. Godse, an ex Rashtriya Swayamsevak Sangh member from Pune, Maharashtra, thought Gandhi favored the political demands of India's Muslims during the partition of India. He plotted the assassination with Narayan Apte and six others. After a trial that lasted over a year, Godse was sentenced to death on 8 November 1949. Although pleas for commutation were made by Gandhi's two sons, Manilal Gandhi and Ramdas Gandhi, they were turned down by India's prime minister Jawaharlal Nehru, deputy prime minister Vallabhbhai Patel and the Governor-General Chakravarti Rajagopalachari, and Godse was hanged in the Ambala jail on 15 November 1949.
