A future Kentucky governor attempted biological warfare in the Civil War
Dr. Luke Blackburn was a respected medical doctor and philanthropist until he allegedly attempted to create a yellow fever outbreak targeting Northern civilians and soldiers during the Civil War. Despite widespread outrage at the time, he later won a landslide victory to become the governor of Kentucky.

Blackburn was a native Kentuckian who began working as a physician after receiving his medical degree from Transylvania University. Early in his career, he implemented a quarantine to shut down a cholera epidemic and he later led another that successfully stopped an outbreak of yellow fever in the Mississippi River Valley. He gave an encore performance against another outbreak in 1854.
But when the tide of the Civil War started going against the South, he found that his loyalty to the Southern cause was greater than his dedication to the Hippocratic Oath.
The vaunted doctor allegedly traveled to Bermuda in 1864 when an epidemic of yellow fever broke out. During this time in the Civil War, the disease was known for striking down cities, killing thousands.
Blackburn helped treat the sick in Bermuda, but he also stole the clothing and bedding of those who died of either yellow fever or smallpox. He then sent trunks of these items to auction places in the North where they were sold and distributed among civilians.
Godfrey Hyams, an Englishman who met Blackburn in Canada, was one of the men paid to smuggle the tainted clothing and bedding into the North. He was promised $100,000 for his services, almost $1.5 million in current dollars.
Hyams was able to sell five trunks of clothing through auctioneers, but only one Union soldier death was attributed to the men and that one was circumstantial. The soldier had died from smallpox after buying clothes at a consignment store that held Blackburn clothing.
The reason that no one died of yellow fever due to Blackburn's actions is that the disease can not be transmitted via the clothing or bedding of its victims, though no one knew it at the time. Oddly enough, the Transylvania-trained doctor would have been more successful if he had recruited more bloodsuckers into his organization. Specifically, he needed female mosquitoes.
Yellow fever is a blood-borne virus spread by certain female mosquitoes. If Blackburn had succeeded in bringing a few victims North for mosquitoes to bite, he may have succeeded in his dark quest. But it wasn't until 1901 that a team led by Maj. Walter Reed proved the connection between mosquitoes and yellow fever, so Blackburn didn't know in 1864 and 1865 that his plan could never work.

But Blackburn was dedicated to his plan. He returned to Bermuda to fill three more trunks with infected clothing and bedding. He contracted a man there, Edward Swan, to send these trunks to the North the following Spring, but Swan was found out and tried.
Meanwhile, Hyams had still not been paid. Hyams finally got tired of waiting and went to the U.S. counsel's office in Toronto to sell out his employer in early April 1865. A public trial filled the newspapers in Canada and throughout the U.S., but Blackburn was eventually acquitted on a technicality.
The trunks had been shipped to Nova Scotia before entering the U.S., and the court that was trying Blackburn did not have jurisdiction over crimes committed there. Meanwhile, the three other trunks from Bermuda were never on Canadian soil.
Blackburn, for his part, did not testify at his trial but said years later that the entire plot was too preposterous for gentlemen to even believe it existed. After his Canadian acquittal, he avoided the U.S. for a time to avoid prosecution, but he went south in 1868 to fight a yellow fever outbreak in Texas and Louisiana.
Prosecutors allowed him to work unmolested and Blackburn went on to fight yellow fever in Tennessee, Florida, and then back in his hometown of Kentucky over the following 10 years. His success fighting the outbreak in Kentucky caused his public image to drastically improve there.
In 1879, he won the gubernatorial election in Kentucky and became the governor. Much of his efforts in that position were aimed at easing prison crowding and bad conditions through pardons and the construction of a new prison. These measures proved unpopular and Blackburn failed to secure the Democratic nomination in 1883. He returned to private life and died in 1887.
