There are multiple competing theories as to how Poe came to be found delirious on a Baltimore street. One of the most popular is that he was the victim of “cooping,” a type of 19th-century voting fraud in which people were kidnapped, plied with alcohol and forced to vote multiple times under different identities. Poe was famously sensitive to alcohol—a glass of wine could allegedly make him violently ill—so the cooping theory could explain his condition and the strange clothes.
Another theory is that Poe wasn’t drunk but suffering from rabies. In 1996, a Baltimore cardiologist diagnosed Poe’s symptoms as typical of encephalitic rabies, also known as “furious rabies,” which is characterized by alternating episodes of confusion, hallucinations, agitation and hydrophobia, the fear of water. According to later accounts by Poe’s attending physician, Dr. John Moran, Poe was perspiring heavily, yelling at imaginary companions and too agitated to take visitors. He could only be convinced to drink water with great effort.
However, neither of these theories explains why Poe was in Baltimore in the first place. Although Poe had lived in Baltimore for several years, he was living in New York City in 1849. After the death of his first wife, Poe reconnected with an old girlfriend who lived in Richmond, Virginia, and they were engaged. On September 27, Poe boarded a steamship from Richmond to New York with a stopover in Baltimore. No one knows what Poe did in Baltimore for five days from September 28 through October 3, when he was found semiconscious on the street.
