Debiprasad Chattopadhyaya was born on 19 November 1918 in Calcutta. His father was a supporter of India's freedom struggle. It was probably his influence that initiated Debiprasad to two major passions in his life – Indian philosophy and politics; he quickly progressed towards radical streams in both fields, developing a lifelong commitment to Marxism and communist movement. At a very early stage of his life Chattopadhyaya immersed himself in the left nationalist movement by joining the Association of Progressive Writers, which was formed in 1936.
