Tryon Reakirt (21 April 1844 – after 1871) was an American businessman and entomologist. He wrote several papers on butterflies and showed great promise in his field. However his career was cut short when financial and legal difficulties forced him to flee the country. The letters also contained hints that Reakirt might move to Rio de Janeiro and reported that he was ill with dysentery. The last evidence of correspondence from Reakirt is an empty envelope with a postal date of November 1872. No further news of Reakirt has ever been uncovered.
