In psychology research literature, the term child prodigy is defined as a person under the age of ten who produces meaningful output in some domain to the level of an adult expert performer. Child prodigies are rare; and, in some domains, there are no child prodigies at all. Prodigiousness in childhood does not always predict adult eminence.
The term Wunderkind (from German: Wunderkind, literally "wonder child") is sometimes used as a synonym for "prodigy", particularly in media accounts. Wunderkind also is used to recognize those who achieve success and acclaim early in their adult careers.
Examples of particularly extreme prodigies could include Wolfgang Amadeus Mozart, Franz Liszt, Felix Mendelssohn, George Enescu, Evgeny Kissin and Teresa Milanollo in music; Bobby Fischer, Samuel Reshevsky, Judit Polgár, Magnus Carlsen, Sergey Karjakin, Paul Morphy and José Capablanca in chess; Carl Friedrich Gauss, Shakuntala Devi, Srinivasa Ramanujan, Ruth Lawrence, János Bólyai, John von Neumann and Terence Tao in mathematics; Rabindranath Tagore in literature; Pablo Picasso and Wang Ximeng in art; Saul Kripke in philosophy; and Blaise Pascal in science. French composer Camille Saint-Saëns has been recognized by musical historians as one of the greatest musical child prodigies, but his mother was cautious, and didn't seek to exploit her son's skills, fearing it would cause him emotional trouble.
