Anthony Comstock arrested many people, but perhaps none was so famous as Madame Restell, whom he arrested on February 11, 1878, for selling contraceptives and abortifacients. Because Restell remains best known as an abortion provider, and because Comstock succeeded in passing a federal statute that bears his name, one might assume that abortion occupied a central place in his campaign, or that Restell was arrested for performing an abortion. Neither is completely accurate. By taking the arrest of Restell as a case study, this post considers the various legal modes by which Comstock did his work, and the way he understood abortion as related to his greater campaign against obscenity and sexual license.
