William James Sidis

William James Sidis (/ˈsaɪdɪs/; April 1, 1898 – July 17, 1944) was an American child prodigy with exceptional mathematical and linguistic skills. He wrote the book The Animate and the Inanimate, published in 1925 (written around 1920), in which he speculated about the origin of life in the context of thermodynamics.

His father, the psychiatrist Boris Sidis, raised his son according to certain principles with the desire for his son to be gifted. Sidis became famous first for his precocity and later for his eccentricity and withdrawal from public life. Eventually, he avoided mathematics altogether, writing on other subjects under a number of pseudonyms. He entered Harvard University at age 11 and, as an adult, was said to have an IQ between 250 and 300, and to be conversant in about 25 languages and dialects. Some of these statements have not been verified, but many of his contemporaries, including Norbert Wiener, Daniel Frost Comstock, and William James, agreed that he was extremely intelligent.
