Clarissa Caldwell Lathrop (1847 – September 11, 1892) was an American social reformer and autobiographer. Her prominence came from her remarkable experience, being confined and unlawfully imprisoned in the Utica Lunatic Asylum for 26 months (October 1880 – December 1882), through a plot of a secret enemy to kill her. She eventually managed to communicate with James Bailey Silkman, a lawyer who, like herself, was confined in the same asylum under similar circumstances. He succeeded in obtaining a writ of habeas corpus, and Judge George G. Barnard of the New York Supreme Court pronounced Lathrop sane and unlawfully incarcerated.
