Innovative Experiment to Combat Airborne Pathogens

In 1937, researchers William and Mildred Wells conducted a groundbreaking experiment at an elementary school to combat airborne pathogens. While UV light was known to kill bacteria on surfaces, the Wellses theorized that infectious diseases could linger in the air for hours. They created 'radiation chambers' in classrooms where UV rays would blast the air to kill off pathogens, marking a significant advancement in combating airborne illnesses.
