A Walkthrough Cholera, London 1854 | The Map That Rewrote Medical History

In 1854, a deadly cholera epidemic exploded through the streets of Soho, London — killing 500 people in just 10 days. No one knew how to stop it. Except one doctor. And all he had was a map. This is the true story of John Snow — the physician who defied the entire medical establishment, went door to door through a plague-ridden neighborhood, and used data to solve one of history's deadliest mysteries. His discovery didn't just end the 1854 Broad Street cholera outbreak. It changed the way humanity understands disease forever.
