Charles Cowlam’s career as a convict, spy, detective, congressional candidate, adventurer, and con artist spanned the Civil War, Reconstruction, and Gilded Age. His life touched many of the most prominent figures of the era, including Abraham Lincoln, Jefferson Davis, and Ulysses S. Grant. One contemporary newspaper reported that Cowlam “has as many aliases as there are letters in the alphabet.” He was a chameleon in a world of strangers, and scholars have overlooked him due to his elusive nature. Reconstruction offered additional opportunities for Cowlam to repackage his identity. He convinced Ulysses S. Grant to appoint him U.S. marshal and persuaded Republicans in Florida to allow him to run for Congress. After losing the election, Cowlam moved to New York, where he became a serial bigamist and started a fake secret society inspired by the burgeoning Granger movement.
