The story
Bhīmrāo Rāmjī Ambedkar was born into a Mahar family, then counted untouchable. He was made to sit apart from the class at school and was not allowed to touch the water tap. He went on to take doctorates at Columbia and the London School of Economics, and to qualify at Gray's Inn.
He chaired the drafting committee of India's constitution, which abolished untouchability in its seventeenth article, and served as the first law minister. He resigned over the Hindu Code Bill, which would have given women rights in property and divorce, when it was blocked.
In October 1956, weeks before his death, he converted to Buddhism at Nagpur with several hundred thousand followers, having said twenty years earlier that he had been born a Hindu but would not die one.
