Sadly, Galton was also the inventor of eugenics, a pseudoscience whose most impactful contribution to the world has been the justification of genocide. By / October 29, 2022 / October 29, 2022 1920s.

Over time, the information got more and more detailed, and the system got more developed (thanks, in part, to another French police officer, Alphonse Bertillon).
