The Tuskegee Syphilis Study: A Dark Chapter in American Medical History

I know that this one is more widely known, but I think it’s important that it’s also captured in this protocol. From 1932 to 1972, the U.S. Public Health Service conducted what is now known as the Tuskegee Syphilis Study—a 40-year-long medical experiment on 600 Black men in Macon County, Alabama, without their informed consent.

The study involved 399 men with syphilis and 201 without. The participants were told they were being treated for “bad blood,” a vague term used to describe a variety of ailments. In reality, they were not treated at all—even after penicillin became the standard cure in 1947.

Doctors withheld treatment and instead tracked the progression of the disease, even as men suffered from severe complications, blindness, mental deterioration, and death. The goal was to observe the natural course of untreated syphilis in Black men.

The men were misled, denied proper medical care, and even prevented from accessing treatment elsewhere. Dozens died, and many of their wives and children were also infected.

The study was exposed in 1972, leading to national outrage and the eventual establishment of stricter ethical guidelines for human research. In 1997, President Bill Clinton formally apologized to the survivors and their families, acknowledging the deep violation of trust and human dignity.

The Tuskegee Study has left a lasting legacy of mistrust toward the healthcare system in many Black communities.
