Remembering SHAKUNTALA DEVI – The Human Computer


Shakuntala Devi was born in Bengaluru, Karnataka State of India on November 4, 1929.

At age 3, it was while playing cards with her father, that he discovered her uncanny ability to memorize numbers.

She dropped out of school because her father, a circus worker, could not afford the monthly school fee of Rs 2.

Shakuntala Devi began demonstrating her math skills at the circus where her father worked as a performer and later in roadshows arranged by him after he quit the circus.

At age 6, she gave her first major show at the University of Mysore.

She became world-famous and she traveled the world, displaying her ability to perform complex calculations in her head, despite having no formal education.

During an event at the University of Rome, the judges declared her answer to a problem as wrong, until the experts re-examined their own calculations and found her to be wright.
