Slide 1 — William Sidis: The World’s Smartest Mind Who Died Alone and Penniless
William James Sidis is often called the smartest person who ever lived. Born in 1898 to Ukrainian immigrant parents, he was said to have an IQ higher than Einstein and to speak 25 languages. He entered Harvard at age 11 and quickly became a worldwide sensation. Yet his greatest mind did not save him from a life of loneliness and poverty. He died at 46, largely forgotten by history. This is the story of a prodigy who dazzled the world and then vanished from it.

Slide 2 — A Prodigy Born into a World Hungry for Genius
Sidis was born in 1898 to Ukrainian immigrant parents. His father, Boris Sidis, a psychiatrist, pushed an accelerated path for his son’s development. The family’s belief in pushing limits helped create a mind that would astonish the world, and yet it also planted the seeds of pressure that followed him his entire life.
Slide 3 — Harvard Fame and Public Scrutiny
In Harvard, the boy became the center of attention. The press called him the new Einstein, and the family allowed journalists to watch and photograph him. Sidis did not crave fame; he wanted to learn and create. But the fame came with a price: curiosity turned to judgment, and a world not prepared for a mind this large began to scrutinize every step he took.
Slide 4 — From Promise to Silence: A Life in Disguise
At 16, Sidis finished university and attempted a career in teaching. The environment was hostile; he was humiliated, rejected, and mocked. Society treated him as an adult genius, not a child prodigy. After a string of setbacks, he changed his name, moved away, and lived in anonymity, taking jobs as an archivist, a bookkeeper, and a laborer. His IQ ceased to be a talking point. He wrote under pseudonyms, studied transit systems, kept diaries, and stopped attending scientific conferences.
Slide 5 — A Tragic End, and a Silent Legacy
He did not break intellectually; he broke under social pressure. Sidis became a symbol that the world is not ready for true genius. In 1944, he died of a stroke in a rented room, at 46, with no family and little recognition. He lived in the shadows, with the planet’s highest IQ, and yet vanished from history. Would you want to be the smartest in the world if it meant loneliness? Is intellect a gift or a curse? Genius or normal—what would you choose?
