Kim Peek

Peek was born in Salt Lake City, Utah, with macrocephaly, damage to the cerebellum, and agenesis of the corpus callosum, a condition in which the bundle of nerves that connects the two hemispheres of the brain is missing; in Peek's case, secondary connectors such as the anterior commissure were also missing. There is speculation that his neurons made unusual connections due to the absence of a corpus callosum, resulting in an increased memory capacity. According to Peek's father, Fran (Francis) Peek, Kim was able to memorize things from the age of 16–20 months. He read books, memorized them, and then placed them upside down on the shelf to show that he had finished reading them, a practice he maintained all his life. He could speed through a book in about an hour and remember almost everything he had read, memorizing vast amounts of information in subjects ranging from history and literature, geography and numbers to sports, music and dates. Peek read by scanning the left page with his left eye, then the right page with his right eye. According to an article in The Times newspaper, he could accurately recall the contents of at least 12,000 books. Peek lived in Murray, Utah, and spent a considerable amount of his time reading at the Salt Lake City Library and demonstrating his capabilities at schools, with great help from his father.

Peek died of a heart attack at his home on December 19, 2009, aged 58. His father, Fran, died on April 5, 2014, aged 88.

A 2008 study concluded that Peek probably had FG syndrome, a rare X chromosome-linked genetic syndrome that causes physical anomalies such as hypotonia (low muscle tone) and macrocephaly (abnormally large head).

In 2004, scientists at the Center for Bioinformatics Space Life Sciences at the NASA Ames Research Center examined Peek with a series of tests including computed tomography (CT scan) and magnetic resonance imaging (MRI). The intent was to create a three-dimensional view of his brain structure and to compare the images to MRI scans performed in 1988. These were the first tentative approaches in using non-invasive technology to further investigate Kim's savant abilities.

In 1984, screenwriter Barry Morrow met Peek in Arlington, Texas; the result of the meeting was the 1988 Academy Award winning film Rain Man. The character of Raymond Babbitt, although inspired by Peek, was depicted as being autistic. Dustin Hoffman, who portrayed Babbitt in the film, met Peek and other savants to get an understanding of their nature and to play the role as accurately and methodically as possible. The movie led to a number of requests for appearances, which increased Peek's self-confidence. Barry Morrow gave Peek his Oscar statuette to carry with him and show at these appearances; it has since been referred to as the "Most Loved Oscar Statue" because it has been held by more people than any other. Peek also enjoyed approaching strangers and showing them his talent for calendar calculations by telling them on which day of the week they were born and what news items were on the front page of major newspapers that day. Peek also appeared on television. He travelled with his father, who took care of him and performed many motor tasks that Peek found difficult.

Laurence Kim Peek (November 11, 1951 – December 19, 2009) was an American savant. Known as a "megasavant", he had an exceptional memory, but he also experienced social difficulties, possibly resulting from a developmental disability related to congenital brain abnormalities. He was the inspiration for the autistic savant character Raymond Babbitt in the movie Rain Man. Although Peek was previously diagnosed with autism, it is now thought that he instead had FG syndrome.
