Shakuntala Devi [November 4, 1929 – April 21, 2013] an Indian Mathematician , also known as “Human Computer” was a child prodigy and mental calculator who has earned a place at The Guinness Book of World Records in 1982. I really love the Shakuntala Devi Puzzles as they are Tricky and Mild boggling. She born in Bangalore on November 4, 1929 and Died on April 21, 2013 . Shakuntala Devi Death was due to Respiratory Problems.
