Origins and History

The beginnings of what we now call the National Institute of Health can be traced to the late 19th century, a time when medicine was still developing and infectious diseases were among the leading causes of death. In 1887, a small experimental lab was started on Staten Island, New York, as part of the Marine Hospital Service. Its original task was simple yet critical: study dangerous microbes and find ways to protect the public.

Over the next few decades, the laboratory steadily expanded. As new epidemics emerged—such as the 1918 influenza pandemic and widespread tuberculosis—the need for advanced biomedical research became undeniable. The laboratory was soon relocated to Washington, D.C., and later found a permanent home in Bethesda, Maryland. A defining moment came in 1930, when U.S. lawmakers passed the Ransdell Act, officially renaming the Hygienic Laboratory as the National Institute of Health. This marked its evolution from a small government lab into a national symbol of scientific advancement.

From that point forward, the NIH grew alongside the challenges it was called to face. During World War II, its researchers supported the war effort by developing treatments and vaccines for military personnel. In the decades after the war, the institute transformed into a broad system of specialized centers, each dedicated to tackling specific health concerns such as cancer, mental illness, cardiovascular disease, and infectious outbreaks. By the early 21st century, the NIH had become a trusted global partner in science, working with universities, hospitals, and international health agencies to confront new crises—including the COVID-19 pandemic.

The journey of the NIH reflects the broader story of medicine itself: constant adaptation, resilience in the face of crises, and a commitment to using knowledge to improve lives. From a single lab in the 1800s to a global leader in medical research, its history demonstrates how small beginnings can spark worldwide impact.
