C. Viruthachalam better known by the pseudonym Pudhumaipithan (also spelt as Pudumaipithan or Puthumaippiththan), was one of the most influential and revolutionary writers of Tamil fiction. His works were characterized by social satire, progressive thinking and outspoken criticism of accepted conventions. Contemporary writers and critics found it difficult to accept his views and his works were received with extreme hostility. He is an individual and his works have been extensively reviewed and debated for over sixty years since his death. His influence has been accepted and appreciated by present-day writers and critics of Tamil fiction. In 2002, the Government of Tamil Nadu nationalised the works of Pudumaippithan.
His career as a writer began in 1933 with an essay "Gulabjaan Kaadhal" (Love for Gulab jamun) published in the magazine Gandhi. His first short story "Aatrangarai Pillaiyaar" (Pillaiyaar on the river bank) was published in 1934 in "Manikodi" and from then on his short stories appeared regularly in it. His short stories appeared in a number of magazines like Kalaimakal, Jothi, Sudantira Chanku, Oozhiyan and Thamizh Mani and the annual issue of Dina Mani. He worked briefly as a sub-editor at Oozhiyan and later at Dina Mani. In 1943, he left Dina Mani to join Dinasari.
In 1940, his book "Pudhumaipithan Kadhaigal" (The stories of Pudhumaipithan), an anthology of his short stories was published. He slowly ventured into the world of Tamil cinema and worked as a scriptwriter in the films Avvaiyaar and KaamaValli. In 1945, he started "Parvatha Kumari Productions" and made an abortive attempt at producing a film called "Vasanthavalli". While working on the movie "Raja Mukthi", in Pune he contracted tuberculosis. He died on 5 May 1948 at Thiruvananthapuram.
