Solomon Shereshevsky (1886-1958) was a Russian journalist and mnemonist active in the 1920s. He was the subject of many behavioral studies for his amazing memory performances. Most of them were carried out by the neuropsychologist Alexander Luria. Luria became interested in him at a work meeting after noticing he did not take any notes and that to everybody's astonishment he could recall the whole speech word by word. Luria studied his memory over a period of more than 30 years. Although he was not recognized as autistic by Luria, Solomon is today widely believed to have been autistic. He had trouble recognizing faces for example. He obviously also suffered from sensory overload. In his book The Mind of the Mnemonist for example Luria mentions the following anecdote from his life (Solomon's own words): "One time I went to buy some ice cream ... I walked over to the vendor and asked her what kind of ice cream she had. 'Fruit ice cream,' she said. But she answered in such a tone that a whole pile of coals, of black cinders, came bursting out of her mouth, and I couldn't bring myself to buy any ice cream after she had answered in that way ..."
