On this date in 1887 mathematician Srinivasa Ramanujan was born in Erode, Tamil Nadu, India. Ramanujan had nearly no formal training in mathematics and was largely self-taught until he was a teenager. As an adult his work quickly gained attention from other Indian mathematicians who spread his work to Europe. He independently proved several theorems in a number of mathematical subjects and also produced many new theorems. He moved to England in 1914 and continued to publish on a wide range of topics and much of his work has been widely influential for his unique approaches to even already established proofs.
