Yes, I know you mean eugenics. But that fundamentally isn't science. It's government policy. You are blaming this on science, so please point me to the science that you blame this on.
Eugenics is the name of a scientific theory, part of "scientific racism", first formulated by Francis Galton, a half-cousin of Darwin. See 1865 article "Hereditary Talent and Character", and 1869 book "Hereditary Genius".
Make sure you research on the science and history of eugenics instead of seeking support for your prejudice about it. Of course, it's a shameful example of accepted but disastrous "science", which social scientists, media and politicians don't like to talk about. They always have many theories, to provide room for plausible deniability, but eugenics was accepted no less than any other social theory at the time.
That theory was significantly expanded later and used by politicians in the US to justify forced sterilization of Irish and black women (not sure about others - DO research"),
It was also used and adapted by Hitler to justify his racial believes and policies.
No one considers eugenics science. Just because some guy in the 1800s said it was science doesn't make it so. Next you'll say Scientology is science... Or astrology, or whatever. We have a pretty defined view of what science is today and any random person calling something science doesn't discredit actual science.
No one considers eugenics science NOW, but it was considered science back then and we're commenting on modern scientific studies that would be adopted wholesale by the eugenics scientists of the time.
It doesn't matter what you call it, if it walks like eugenics, if talks like eugenics it is eugenics even if that word was thrown out as politically inconvenient. Go back to my first comment in this thread and understand it in this light.

It continued well into 1900's up until WW2 and it was a social theory as scientific as any other at the time, otherwise it would not be used for justification of government policies.
This is definitely not true. There are hereditarian scientists working to rehabilitate "eugenics"; this comes up a lot with the people working on embryo selection.
Eugenics is a simple concept that is morally neutral. Embryo selection or forced sterilizations are implementation details that are absolutely not morally neutral. But when most people say "eugenics" it seems like they are usually referring to the particular implementation with forced sterilizations.
That's not science. The actual study of genetic inheritance is science. Eugenics is just saying "hey, that means we can breed humans like any other animal." And forced sterilization is an implementation detail that isn't even inherent in the concept itself. Blaming this on science is like blaming a shooting on science because ballistics, chemistry, and metallurgy are sciences.
Eugenics was flourishing during Hitler's time, he loved it, it was the foundation and the excuse for his believes.
