<human>: Born on 1 September 1896, the day after Janmastami ,one of the most important Vaishnava holidays, in a humble house in the Tollygunge suburb of Calcutta in a Bengali Suvarna Banik family, he was named Abhay Charan, "one who is fearless, having taken shelter at Lord Krishna's feet." Since he was born on the day of Nandotsava ("the celebration of Nanda," Krishna's father, a traditional festival in honour of Krishna's birth) he was also called Nandulal. His parents, Sriman Gour Mohan De and Srimati Rajani De, were devout Vaishnavas (devotees of Vishnu). In accordance with Bengali tradition, his mother had gone to the home of her parents for the delivery, and only a few days later Abhay returned with parents to his home at 6 Sitakanta Banerjee Lane Kolkata 700005  He received a European-led education in the Scottish Church College, which was well reputed among Bengalis; many Vaishnava families sent their sons there. The professors, most of whom were Europeans, were known as sober, moral men, and it is believed that the students received a good education. The college was located in north Calcutta, near the De's family home on Harrison Road. During his years in the college, Abhay Charan De (abhy' crnn de) was a member of the English Society as well as that of the Sanskrit Society, and it has been suggested that his education provided him a foundation for his future leadership. He graduated in 1920 with majors in English, philosophy and economics. He rejected his diploma in response to Gandhi's independence movement.  At 22 years of age he married Radharani Devi, who was then 11 years old, in a marriage arranged by their parents. At 14, she gave birth to Abhay's first son. CANNOTANSWER
