Abhay Charanaravinda Bhaktivedanta Swami Prabhupada (Abhoy Charonarobindo Bhoktibedanto Shwamy Probhupad; 1 September 1896 - 14 November 1977) was a Gaudiya Vaishnavism spiritual teacher (guru) and the founder preceptor (Acharya) of the International Society for Krishna Consciousness (ISKCON), commonly known as the "Hare Krishna Movement". Adherents of the ISKCON movement view Prabhupada as a divine avatar and messenger of Krishna. Born Abhay Charan De in Calcutta, he was educated at the Scottish Church College in Calcutta. Before adopting the life of a pious renunciant (vanaprastha) in 1950, he was married with children and owned a small pharmaceutical business.

In 1922, when he first met his spiritual master, Bhaktisiddhanta Sarasvati Thakura, he was requested to spread the message of Chaitanya Mahaprabhu in the English language. In 1933 he became a formally initiated disciple of Bhaktisiddhanta. In 1944, (from his front room at Sita Kanta Banerjee, Calcutta), he started the publication called Back to Godhead, for which he acted as writer, designer, publisher, editor, copy editor and distributor. He personally designed the logo, an effulgent figure of Chaitanya Mahaprabhu in the upper left corner, with the motto: "Godhead is Light, Nescience is darkness" greeting the readers. In his first magazine he wrote:  Under the circumstances since 1936 up to now, I was simply speculating whether I shall venture this difficult task and that without any means and capacity; but as none have discouraged me, I have now taken courage to take up the work.  In 1947, the Gaudiya Vaishnava Society recognised his scholarship with the title Bhaktivedanta, (bhakti-vedanta) meaning "one who has realised that devotional service to the Supreme Lord is the end of all knowledge" (with the words Bhakti, indicating devotion and Vedanta indicating conclusive knowledge).  His later well known name, Prabhupada, is a Sanskrit title, literally meaning "he who has taken the shelter of the lotus feet of the Lord" where prabhu denotes "Lord", and pada means "taking shelter." Also, "at whose feet masters sit". This name was used as a respectful form of address by his disciples from late 1967 early 1968 onwards. Previous to this, as with his early disciples, followers used to call him "Swamiji".  From 1950 onwards, he lived at the medieval Radha-Damodar mandir in the holy town of Vrindavan, where he began his commentary and translation work of the Sanskrit work Bhagavata Purana. Of all notable Vrindavana's temples, the Radha-Damodara mandir had at the time the largest collection of various copies of the original writings of the Six Gosvamis and their followers - more than two thousand separate manuscripts, many of them three hundred, some even four hundred years old. His guru, Bhaktisiddhanta Sarasvati Thakura, had always encouraged him to print books, and beholding his spiritual master, Abhay felt the words deeply enter his own life - "If you ever get money, print books."  referring to the need of literary presentation of the Vaishnava culture.
