Shakuntala Devi was born in Bangalore – Karnataka, India, to an orthodox priestly Kannada family. Her father rebelled against becoming a temple priest and instead joined a circus, where he worked as a trapeze and tightrope performer, and later as a lion tamer and a human cannonball. Shakuntala Devi was only around three years old and she was roped in to help her father with card tricks. Her father left the circus and took her on road shows that displayed her amazing ability at number crunching. Her calculating gifts first demonstrated themselves while she was doing card tricks with her father when she was three. They report she “beat” them by memorization of cards rather than by sleight of hand. By age six she demonstrated her calculation and memorization abilities at the University of Mysore. At the age of eight she had success at Annamalai University by doing the same. In 2006 she released In the Wonderland of Numbers with Orient Paperbacks which talks about a girl Neha and her fascination for numbers. She developed the concept of `mind dynamics’.
