In the sweltering summer of 1888, a Tampa saloon keeper named R.D. McCormick stepped off a train in Jacksonville, Florida, carrying something far deadlier than luggage. Within weeks, the disease known as Yellow Jack would transform America's booming winter playground into a quarantined city of the dead, sending refugees fleeing north only to be met with armed guards, locked gates, and threats of gunfire. Of the roughly fourteen thousand people who stayed, one in three would contract yellow fever. Four hundred and twenty-seven would never recover.

Jacksonville in 1888 was no ordinary Southern city. A progressive coalition of working-class whites and African Americans had swept the previous year's election, seating five Black council members, a Black municipal judge, and twenty-three Black police officers. The epidemic shattered that experiment in biracial governance. As elected officials fled, civilian leaders stepped forward. Colonel J.J. Daniel organized the Jacksonville Auxiliary Sanitary Association, hiring hundreds of doctors and nurses before the fever claimed his own life. Dr. Alexander Darnes, Jacksonville's first African American physician, stayed to treat patients from both communities. A woman known as Mrs. A.B. Anthony went house to house delivering milk to the sick at her own expense.
