Personal Life

Shakuntala Devi was born in Bengaluru, India, on 4 November 1929 to an orthodox Kannada Brahmin family. Her father was a traveling magician who had rebelled against his traditional family to pursue this unconventional profession instead of becoming a priest or astrologer as his forefathers had been.

Childhood & Early Life

Her family was a very poor one as her father hardly made enough to make ends meet. She could not even receive a formal education because of her family’s dire financial situation.

Childhood & Early Life

According to an anecdote, she started playing card games with her father when she was three years old. Her father realized that the little girl won all the games against him every day and suspected that she was cheating. He closely studied her as she played and realized that she was memorizing all the card numbers and their sequence as the game progressed in the initial rounds and used this knowledge to win the game.

Later Years

In 1955, she appeared on a BBC show where the host Leslie Mitchell gave her a complex math problem to solve. She solved it in seconds but the host told her that her answer was incorrect as her answer was different from what the host and his team had calculated.

Mitchell then rechecked the answer and realized that Devi’s answer was the correct one and the original answer was wrong. This news spread across the world and Shakuntala earned the title of the 'Human Computer'.

Later Years

She was often invited by educational institutions and in 1977 she visited the Southern Methodist University in Dallas, USA. There she was asked to calculate the 23rd root of a 201-digit number, which she solved in 50 seconds. It had taken four minutes for a professor to write the problem on the board, and it took more than a minute for a Univac computer to solve it.

Later Years

She was also a successful astrologer and authored several books on the subject. In addition she also wrote texts on mathematics for children and puzzles. One of her most significant books was ‘The World of Homosexuals’ (1977) which is the first comprehensive study of homosexuality in India. The realization that her husband was a homosexual had made her look at homosexuality more closely.

Shakuntala Devi is best remembered for demonstrating the multiplication of two randomly picked 13-digit numbers—7,686,369,774,870 × 2,465,099,745,779 on 18 June 1980. She correctly gave the answer as 18,947,668,177,995,426,462,773,730 in 28 seconds. This unbelievable feat of hers earned her a place in the ‘Guinness Book of Records’ in 1982.
