# Periyar Dasan

Dr. Periyar Dasan or Dr. Abdullah (born Seshachalam; 21 August 1949 – 19 August 2013) was an Indian scholar, professor, eminent speaker, and activist from Tamil Nadu. He propagated atheism and rationalist ideologies for most part of his life and later converted to Islam. He has also appeared in around 15 Tamil-language films.

## Early life and background

Seshachalam was born in a Shaivite family on 21 August 1949 at Agaram in Perambur, a neighbourhood in present-day Chennai, Tamil Nadu, India. He was attracted towards the rationalist ideals of Periyar E. V. Ramasamy, the founder of the Dravidian movement. During his days in Pachaiyappa’s College, he changed his original name to Periyar Dasan (ardent follower of Periyar). He was well-versed in Tamil literature, various religious studies, and English. He has authored around 120 books. He served as a professor in his alma mater, Pachaiyappa’s College, for 34 years and as a corporate trainer, psychologist, psychotherapist, and students counsellor for many years.
In 1991, Dasan embraced Buddhism and added Siddhartha as a prefix to his name. He translated the Dhammapada, a compilation of Buddhist virtues, authored by B. R. Ambedkar, into Tamil. This took him to learn Pali and Sanskrit.
Taking everyone by surprise, he embraced Islam as his way of life on 11 March 2010 during a visit to Mecca and rechristened his name as Abdullah, and his wife Vasantha was given the name Fathima. Thereafter, he started giving a series of lectures on Islam. Before embracing Islam, he spent 10 years knowing the key aspects of that religion and learning the Quran and the Arabic language.
