Page "William James Sidis" Paragraph 15

It has been acknowledged that Helena and William's mother Sarah had developed a reputation to exaggerate claims about the Sidis family.

Helena had also falsely claimed that the Civil Service exam William took in 1933 was an IQ test and that his ranking of 254 was an IQ score of 254.

Helena also claimed that " Billy knew all the languages in the world, while my father only knew twenty-seven.

I wonder if there were any Billy didn ’ t know.

" This claim was not backed by any other source outside the Sidis family and Sarah Sidis also made an improbable claim in her 1950 book The Sidis Story that William could learn a language in just one day.
