How fatal was TB in the 1800s?

The Shadow of Tuberculosis: How the "Robber of Youth" Devastated the 1800s

Long before modern antibiotics transformed it into a treatable illness, tuberculosis (TB) was one of the most feared killers in the Western world. Throughout the 18th and 19th centuries, the disease tore through rapidly growing cities, thriving in crowded, poorly ventilated tenements born of the Industrial Revolution. Its toll was nothing short of catastrophic.

At its peak in Western Europe, tuberculosis reached epidemic proportions, boasting a staggering mortality rate of up to 900 deaths per 100,000 inhabitants each year. What made the bacterial infection particularly heartbreaking was its target demographic. Unlike many infectious diseases that primarily claim the elderly or infants, TB preyed relentlessly on young adults in the prime of their lives. This devastating characteristic earned the affliction a chilling moniker: "the robber of youth."

For families during the 1800s, a diagnosis was often seen as a slow death sentence. Known colloquially as "consumption" due to the way it seemed to consume the body from within, the disease left a profound mark on Victorian culture, art, and medicine. It wasn't until Robert Koch discovered the bacterium Mycobacterium tuberculosis in 1882 that humanity finally understood its true cause, paving the way for the sanatorium movement and the eventual medical breakthroughs that brought this deadly scourge under control.
