The Year Humans Forgot How to Breathe – London’s Killer Smog vs. Copenhagen’s Last-Hand Ventilation

In 1952, two cities rewrote the biology of breath. London was swallowed by a greasy, sulfur-yellow fog that killed 12,000 people in five days—proving the air itself could murder. On the same calendar page, Copenhagen’s polio surge filled a single ward with children whose own diaphragms had quit. With only one iron lung for dozens of paralyzed kids, anesthesiologist Bjørn Ibsen ditched the “negative-pressure” dogma, slit a 12-year-old girl’s throat, and hand-squeezed a rubber bag for 24 hours—sparking positive-pressure ventilation, the world’s first ICU, and the birth of modern critical-care medicine. Trace the 200-year road from Priestley’s “de-phlogisticated air” and Lavoisier’s guillotine to iron lungs, iron smog, and the ventilators that fought COVID-19—while climate wildfires and antibiotic-resistant pneumonia wait in the next breath. #HistoryOfMedicine #LondonSmog #Polio #MechanicalVentilation #ICU #ClimateAndHealth
