Quoting A is Me:" I wouldn't be surprised if they were performed on the less than competent, like mentally ill patients, etc..."
There was a lot of talk about eugenics in the 1920's. It was, to oversimplify, the idea that only wealthy, healthy white people should be encouraged to reproduce and there were "eugenics programs" for poor and non-white people. This was right here in America too, that Nazi stuff didn't seem so absurd until millions of people were being murdered over it.
So whoever made the point about WWII and the Nazis, good thinking. As much as I hate to say it, I'm sure the medical industry made huge strides during that time. Ugh, so gross.
And of course we're all speculating. Last summer I contacted every school, museum, and historian who I thought could possibly have any information about this and they all slammed their doors in my face. If anybody still knows, they're not going to discuss it.
My great grandmother died after a botched abortion in 1925. She died in the only Women's Medical College in America at that time. When she was taken to the hospital, she was well enough to stand at the window and wave goodbye to her kids, which makes me wonder if it wasn't actually a homemade or back-alley situation. They lived in poverty and it was at least her 8th pregnancy. I'll never know what happened, but I'll always wonder.
