Kim Peek was the basis for the 1988 fictional film Rain Man because he was a megasavant.
A prodigious savant is someone whose skill level would qualify him or her as a prodigy, or exceptional talent, even in the absence of a cognitive disability. Prodigious savants are those individuals whose abilities would be considered phenomenal or genius even in a person without any limitations or special diagnosis of impairment. The most common trait of these prodigious savants is their seemingly limitless mnemonic skills, with many having eidetic or photographic memories. Indeed, prodigious savants are extremely rare, with fewer than one hundred noted in more than a century of literature on the subject. Treffert, the leading researcher in the study of savant syndrome, estimates that fewer than fifty or so such individuals are believed to be alive in the world today. The website of the Wisconsin Medical Society lists 29 savant profiles. Darold Treffert is past-president of the society.
