During World War II, two Polish doctors found a way to save lives without firing a shot. Dr. Eugene Lazowski and his colleague Dr. Stanisław Matulewicz discovered that a harmless bacterium, Proteus OX19, could create a false positive on the standard Nazi test for typhus. The patient stayed healthy, but the test result looked dangerous.

The idea was simple and brave. If the Nazis believed a town was full of typhus, they would quarantine the area and avoid it. Deportations would stop. Roundups would slow or disappear entirely. People would live.

The doctors quietly injected people throughout Rozwadów and nearby villages, creating what looked like a spreading epidemic. When German health officials arrived to inspect the situation, the blood tests confirmed exactly what the doctors intended. Fearing infection, the Nazis sealed off the region and kept their distance.

Historians estimate that more than eight thousand people were protected by the fabricated outbreak. This included both Jewish and non Jewish residents who would otherwise have faced forced labor or deportation.

After the war, Dr. Lazowski eventually moved to the United States and became a professor of pediatrics. His story remained largely unknown for decades, yet it stands as one of the most remarkable examples of medical courage in the war.
