An autistic savant is a term used for the person who has both autism and another condition called Savant Syndrome. People with Savant Syndrome has serious developmental or mental infirmities coupled at the same time with certain extraordinary skills. Such skills may include exceptional memory, arithmetical abilities, extraordinary skills in art or music. The special abilities of autistic savant are recognized generally during childhood in children with autism and other developmental difficulties.
In an article entitled "Savant Syndrome: An Extraordinary Condition", Darold A. Treffert, MD, describes Autistic savant which he termed as Savant Syndrome, in these words:
"Savant syndrome is a rare, but extraordinary, condition in which persons with serious mental disabilities, including autistic disorder, have some "island of genius" that stands in marked, incongruous contrast to the overall handicap. As many as one in 10 persons with autistic disorder have such remarkable abilities in varying degrees, although savant syndrome occurs in other developmental disabilities or in other instances of CNS injury or disease as well. Whatever the particular savant skill, it is always linked to massive memory."
Around 10% of autistic people display autistic savant abilities while such abilities are around 1% in non-autistic people (including persons with intellectual disabilities). An autistic savant may display their abilities in many ways, mostly in any of the following fields:
- Exceptional memory: Feats of memory may be manifested in several ways. For instance, an autistic savant may recall the names of all presidents, their dates of birth, places of birth, years of presidency, and several other information related to the presidents. Similarly, autistic savants may recall the birth days of a person even after 10 or 20 years.
- Arithmetical abilities: They can calculate mentally incredibly fast, additions of large numbers, square roots, calculating what day of the week a day in a particular date was or will be in seconds, and so on.
- Extraordinary skills in art: Some autistic savants display extraordinary skills in art and drawing
- Extraordinary skills in music: Music is another extraordinary ability which some autistic savant may possess.
- Around 10% of autistic people and people with related disabilities are estimated to have autistic savant abilities.
- Skill range
- Skill range cover a wide spectrum of skills.
- Typical skills
- Musical and artistic skills, calendar calculating, and many other skills are found in autistic savants. However, rarely more than one skill is pre-dominant except in very few savants.
- Males vs females
- Savant skills are more prevalant in males than in females - six times more in males as compared to females.
- First discovery
- They were present throughout history. However, in modern times, the savant abilities were brought to focus by Dr. Benjamin Rush, often referred to as the father of American Psychiatry, in 1789. However, it was only around a century later in 1887 that Dr. J. Langdon Down presented his observations of three decades of experience as as Superintendent of the Earlswood Asylum in a series of lectures before the Medical Society of London.
There are many famous autistic savants including the following:
- Gottfried Mind (1768–17 November, 1814) was an autistic savant who was a gifted painter. He created many paintings of animals.
- Temple Grandin(b. 1947) is an associate professor at Colorado State University and a famous and successful adult with autism. Grandin is also a successful professional designer of humane livestock facilities.
- Kim Peek(born November 11, 1951), is a unique savant who is able to display many abilities associated with autistic savants - he has a photographic memory; can read an average size book in about one hour and can recall around 98% of the same; he can recall names of the around 12,000 books; he has fantastic mathematical abilities. He is not considered autistic.
Although Kim Peek's initial diagnosis of autism was later changed, Osche believed his message about acceptance of differences would be particularly relevant to the group. 
- Aleksander Vinter (born 1986) a Norwegian musician with prodigious musical abilities. In his lifetime he has claimed to have made over 10,000 songs
- Stephen Wiltshire(born 1974) is an accomplished architectural artist.
