William James Sidis: The Rise and Fall of a Child Prodigy

Born in Boston in 1898 to Jewish immigrant parents Boris and Sarah Sidis, William James Sidis was reading the New York Times at 18 months, spoke eight languages by age eight, and enrolled at Harvard at eleven, where he lectured the Mathematical Club on four-dimensional bodies. This deep dive traces how an intensive experiment in forced early development produced one of the most celebrated minds of a generation.We follow Sidis from academic triumph to a deliberate pursuit of obscurity, examining the crushing weight of public expectation and his lifelong fight to be left alone.
