Source-derived summary

William James Sidis (; April 1, 1898 – July 17, 1944) was an American child prodigy with mathematical and linguistic skills. He was active as a mathematician, linguist, historian, and author. He wrote the book The Animate and the Inanimate, published in 1925, in which he speculated about the origin of life in the context of thermodynamics. His works were published under various pseudonyms, as he never used his real name as an author.

His father, the psychologist 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 claimed by family members to have an IQ between 250 and 300, and to be conversant in about 25 languages and dialects. These statements have not been verified, but many of his contemporaries, including Norbert Wiener and Daniel Frost Comstock, agreed that he was extremely intelligent. He retreated from public life after being arrested and tried for his presence at a socialist parade and died young from a brain hemorrhage.

Editorial analysis

Why this record matters

The phrase “american child prodigy (1898-1944)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q313603. VIAF identifies the subject as 22945139. The Library of Congress control number is n85213744. 3 of 4 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1898, 1944 and 1925.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
