Abolitionist Theodore D. Weld publishes text calling out medical experimentation on enslaved African people.
Date: 1839
In American Slavery As It Is: Testimony of a Thousand Witnesses, Weld writes: "'Public opinion' would tolerate surgical experiments, operations, processes, performed upon them [enslaved people], which it would execrate if performed upon their master or other whites."
This kind of resistance to medical experimentation on enslaved people is highly unusual among white abolitionists in this period.
