Short answers, pulled from the story.
According to unverified accounts, Napoleon's penis was allegedly removed during his autopsy on Saint Helena on the 5th of May, 1821, possibly by his physician François Carlo Antommarchi. It then passed to Napoleon's chaplain, who brought it to Corsica, and later changed hands through booksellers and collectors across two centuries.
The item is owned by the family of John K. Lattimer, a urologist and artifact collector who purchased it in 1977 for $3,000. His daughter inherited it after his death and has reportedly turned down offers of at least $100,000.
Lattimer paid $3,000 for the item in 1977. After his death, his daughter inherited it and has been offered at least $100,000 by prospective buyers.
Yes. A. S. W. Rosenbach, a Philadelphia-based bookseller, displayed the item at the Museum of French Art in New York City in 1927. A reviewer from Time magazine compared it to a "maltreated strip of buckskin shoelace."
The Channel 4 documentary Dead Famous DNA measured the preserved item at 3.8 cm. Judith Pascoe, writing in The New York Times, described it as "barely recognizable as a human body part."
Its authenticity is unclear and disputed. No primary source from Saint Helena records the removal of Napoleon's penis during his autopsy, and Napoleon's biographer Philip Dwyer called the amputation claim "highly fanciful." The current owner has allowed only ten people to view the item and has never permitted it to be recorded on camera.
