Joe Rogan Experience #2563 - Dan Richards · Aired Oct 8, 2026
Claim summary · not a verbatim quotation
Sir Isaac Newton was an alchemist and died of mercury poisoning.
The finding
What the evidence shows
Newton did conduct extensive alchemical work. The claim that mercury poisoning killed him is not established: the contemporary Fontenelle biography records doctors identifying stone disease during his final illness. That historical account supports a different reported terminal condition, but is not a modern definitive autopsy. Alchemy and suspected mercury exposure should not be merged into a proven cause of death.
