How racism creeps into medicine

In 1864, the year before the Civil War ended, a massive study was launched to quantify the bodies of Union soldiers. One key finding in what would become a 613-page report was that soldiers classified as "White" had a higher lung capacity than those labeled "Full Blacks" or "Mulattoes." The study relied on the spirometer—a medical instrument that measures lung capacity. This device was previously used by plantation physicians to show that black slaves had weaker lungs than white citizens. The Civil War study seemed to validate this view. As early as Thomas Jefferson's Notes on the State of Virginia, in which he remarked on the dysfunction of the "pulmonary apparatus" of blacks, lungs were used as a marker of difference, a sign that black bodies were fit for the field and little else.
