Albert Einstein explicitly requested cremation — he wanted no monuments, no shrines, no relics. But during his autopsy, pathologist Thomas Harvey quietly removed Einstein’s brain, placed it in a jar, and disappeared with it for decades. What followed was one of the strangest episodes in the history of science: a stolen organ, a ruined career, and a quest to find genius in gray matter.

This episode traces the bizarre journey of Einstein’s brain from a Princeton hospital to mason jars in a cider box, through decades of dubious research, cross-country road trips, and the ethical questions that still surround the theft of a dead man’s most famous organ.

• How pathologist Thomas Harvey stole Einstein’s brain against the physicist’s explicit wishes
• The decades-long odyssey of brain samples stored in jars, basements, and car trunks
• Scientific studies that claimed to find structural differences in Einstein’s brain
• The ethical firestorm over consent, ownership, and the commodification of genius
