In the 1700s human dissection was a big taboo—people feared that it would leave their bodies mangled on Judgment Day, when God would raise the dead. As a result, government officials banned most dissections. This led to some unintended consequences, most notably a shortage of bodies for anatomists to dissect. To meet the heightened demand, a new profession emerged: grave-robbers. These so-called resurrectionists dug up the bodies of poor people to sell to anatomists, which led to riots in the streets.
