Ezra Lovett

Ezra Lovett was a young man in Beverly, Massachusetts, whom Samuel Thomson treated for a severe cold that Thomson suspected was typhus fever, the same illness that had recently killed Thomson’s own mother. By Thomson’s own account, he attended Lovett, saw some improvement, then left him in the care of an assistant while called away; when Lovett worsened after exposure to winter cold, Thomson returned, judged the case beyond help, and asked the family to call in other physicians, who attended Lovett until his death the following night. By December 1809, a rival physician had Thomson indicted for Lovett’s murder by lobelia, “a deadly poison” (Thomson’s own narrative describes the death as roughly contemporaneous with the fall of 1808, though it also characterizes the indictment as coming two years after the death, an inexactness in the primary source itself). At trial in Salem, a defense attorney chewed a sample of the alleged poison in open court, and the botanist Manasseh Cutler testified that the substance the prosecution had produced was not lobelia at all but marsh rosemary. The jury acquitted Thomson within minutes.
