Basically, there's an immortal cell line that helped immensely in cellular and disease research. It was used to develop the polio vaccine. It's extensively utilized in cancer research as it's ability to reproduce rapidly can be used as a template for tumors.

However, the scientists that took these cells from a dying Henrietta Lacks didn't bother to tell her family that her cells were being used for research. It wasn't until years later where the story came out on how they took these cells for the purpose of research without permission from the patient.

I was wondering if anyone had anyone had any knowledge on any other cases as this one where something was taken from a patient without their permission that dramatically helped the science world?

Did any of his work add to scientific knowledge though? Because it seems as if he did it all out of a megalomania kinda thing
