Srinivasa Ramanujan (22 December 1887 – 26 April 1920) was an Indian mathematician. Though he had almost no formal training in pure mathematics, he made substantial contributions to mathematical analysis, number theory, infinite series, and continued fractions, including solutions to mathematical problems then considered unsolvable.

Tamil Brahmins are an ethnoreligious community of Tamil-speaking Hindu Brahmins, predominantly living in Tamil Nadu, though they number significantly in Telangana, Andhra Pradesh, Kerala, Karnataka, in addition to other regions of India. They can be broadly divided into two denominations: Iyengars, who are adherents of Sri Vaishnavism, and Iyers, who follow the Srauta and Smarta traditions.
