London Before the Outbreak
In the middle of the nineteenth century, London was the largest city in the world, but it was not prepared for that size. Its streets, homes, and water systems belonged to an older age, while its population had grown to nearly two and a half million people. The result was a city crowded with life, trade, noise, and human waste.
A whole class of workers survived by cleaning up what the city threw away. Some searched the river mud for bits of coal, rope, and metal. Others collected dog waste for tanneries, bones for industry, and human waste from cesspools. Their labor formed an improvised recycling system that kept the city from drowning completely in its own refuse.
That system was under growing strain. As London spread outward, it became harder and more expensive to remove waste and carry it to farms or dumping grounds. Many landlords delayed the work, and cesspools overflowed into basements and yards. At the same time, the growing use of indoor toilets sent even more waste into a leaking and badly designed system.
Most people believed the greatest danger came from the smell. Writers, reformers, doctors, and public officials all described London as a place poisoned by stench. They were not wrong about the filth, but they misunderstood the real threat. The smell was awful, yet the more deadly danger was often in the water people drank every day.
Soho stood at the center of this crisis. It was crowded, lively, and socially mixed, with laborers, shopkeepers, artists, and political exiles living side by side. That density gave the neighborhood energy and character, but it also meant that when disease arrived, it could move quickly through the streets and homes.
