How a military surgeon turned blood serum into a weapon against deadly childhood diseases.
In short: Emil von Behring, a Prussian army doctor, revolutionized medicine by discovering that blood serum could neutralize lethal toxins. His breakthrough in serum therapy provided the first effective treatment for diphtheria and tetanus, earning him the inaugural Nobel Prize in Physiology or Medicine in 1901 and saving countless lives.
Born in 1854 to a schoolmaster with 13 children, Emil von Behring’s path to science was forged by financial necessity. Unable to afford a civilian university, he entered the Army Medical College in Berlin in 1874. This military sponsorship required years of service, but it also placed him in the orbit of Robert Koch, the pioneer of bacteriology. By 1890, while working at the Institute for Infectious Diseases, Behring collaborated with Japanese bacteriologist Kitasato Shibasaburō to investigate the nature of bacterial poisons.
The pair discovered that animals injected with graduated doses of sterilized diphtheria or tetanus cultures produced substances in their blood capable of neutralizing those specific toxins. They termed these substances antitoxins. This insight—that the blood of an immunized animal could confer protection or even cure an infected individual—laid the groundwork for passive immunization. While Behring’s initial human trials in 1892 faced setbacks, the refinement of antitoxin production by 1894 allowed for successful clinical application, transforming diphtheria from a terrifying scourge into a treatable condition.
Behring’s career was marked by both scientific brilliance and entrepreneurial ambition. He became a successful businessman, founding the Behringwerke in 1914 to manufacture vaccines and sera. His work extended beyond diphtheria to tuberculosis, where he sought protective agents for humans. Though he was a central figure in the foundation of immunology, his personality often led to friction with contemporaries like Paul Ehrlich and Robert Koch. By the time of his death in 1917, Behring had secured his legacy as a pioneer of public-private partnerships in medicine and a savior of children.
