Udham Singh was a revolutionary nationalist born in 1899 in India who was orphaned as a child. He witnessed the Jallianwala Bagh massacre in 1919 which turned him towards revolution. He illegally brought guns back to India and was imprisoned for four years. He admired Bhagat Singh and sought to avenge the Jallianwala Bagh tragedy. In 1940, he shot and killed Michael O'Dwyer, the former lieutenant governor of Punjab who had endorsed the massacre. Udham Singh did not resist arrest and was hanged for murder in July 1940. His ashes were finally returned to India in 1975 where he was honored.
