Identify

[S.N. Hemanth Meenakshisundaram]

There's a regional slant to this question, hope you folks will still get it:

In 1972, at the age of 19 and in his 2nd year of college, X published his first anthology of poems under a pen name. It was widely lauded and even prescribed as a text at the Women's Christian College, Chennai until it was discovered that the author was just a student in a nearby college. Identify X.

Cheers,
