Popularly known as the ‘Human Computer’, Shakuntala Devi made her way into The Guinness Book of World Records in 1982 for her ability to make mental calculations and solve complicated math problems faster than computer.

Her talent with numbers was first realized by her father, a circus artist, while he was teaching her a card trick when she was about three years old. Her father then quit the circus and set out on road shows to display her ability to make complicated calculations. Shakuntala Devi had, however, got no education.
By the age of six, she demonstrated her calculation and memorization abilities at the University of Mysore.

On June 18, 1980, she demonstrated the multiplication of two 13-digit numbers, 7,686,369,774,870 × 2,465,099,745,779, which were randomly picked by the Computer Department of Imperial College, London. She then provided the correct answer in 28 seconds, which was: 18,947,668,177,995,426,462,773,730.

In addition to her ability to her computer like skills, Shakuntala was also an astrologer and she wrote several books, including cookbooks and novels.
