The Real Story of John Snow

The video explores the life and work of Dr. John Snow, a 19th-century physician known for his pioneering work in epidemiology. It highlights his investigation into the cholera outbreaks in London, where he challenged the prevailing miasma theory by linking the disease to contaminated water. Despite initial skepticism, Snow's methods laid the foundation for modern epidemiology and public health practices. His work, though unrecognized during his lifetime, has saved millions of lives and remains influential today.
