Answer by taking a quote from the following article:

Vijay Dhondopant Tendulkar was born on 6 January 1928 in Girgaon, Mumbai, Maharashtra, where his father held a clerical job and ran a small publishing business. The literary environment at home prompted young Vijay to take up writing. He wrote his first story at age six. He grew up watching western plays and felt inspired to write plays himself.

In his 1972 play, Sakharam Binder (Sakharam, the Binder), Tendulkar dealt with the topic of domination of the male gender over the female. The main character, Sakharam, is a man devoid of ethics and morality, and professes not to believe in "outdated" social codes and conventional marriage. He accordingly uses the society for his own pleasure. He regularly gives "shelter" to abandoned wives and uses them for his sexual gratification while remaining oblivious to the emotional and moral implications of his exploits. He justifies all his acts through claims of modern, unconventional thinking, and comes up with hollow arguments meant in fact to enslave women. Paradoxically, some of the women which Sakharam had enslaved buy into his arguments and simultaneously badly want freedom from their enslavement.  In 1972, Tendulkar wrote another, even much more acclaimed play, Ghashiram Kotwal ("Officer Ghashiram"), which dealt with political violence. The play is a political satire created as a musical drama set in 18th century Pune. It combined traditional Marathi folk music and drama with contemporary theatre techniques, creating a new paradigm for Marathi theatre. The play demonstrates Tendulkar's deep study of group psychology, and it brought him a Jawaharlal Nehru Fellowship (1974-75) for a project titled, "An Enquiry into the Pattern of Growing Violence in Society and Its Relevance to Contemporary Theatre". With over 6,000 performances thus far in its original and translated versions, Ghashiram Kotwal remains one of the longest-running plays in the history of Indian theatre.  Tendulkar wrote screenplays for the movies Nishant (1974), Akrosh (The Cry) (1980), and Ardh Satya (The Half-Truth) (1984) which established him as an important "Chronicler of Violence" of the present. He has written eleven movies in Hindi and eight movies in Marathi. The latter include Samana ("Confrontation") (1975), Simhaasan ("Throne") (1979), and Umbartha ("The Threshold") (1981). The last one is a groundbreaking feature film on women's activism in India. It was directed by Jabbar Patel and stars Smita Patil and Girish Karnad.
