Ironically, a LOT of the local medical data, techniques, and equipment was pretty advanced for this world, at least the stuff Sarah and Adam had stolen from the labs were. Then again, the horrors of the nazi camps progressed a lot of medical feilds as well, and THAT was also a shitshow.
Sorry, I was just catching up, and I can't let this go.
The death and torture camps did not, in fact, advance medical science.
Like, they were ostensibly doing research on how to revive people who were experiencing hypothermia, right? So you want to get a baseline of each victim's medical status: age, weight, sex, blood pressure, etc. Then you want to chill the victim by a particular amount by placing them in water at a specific temperature for a specific length of time. Next, you pick your treatments and record which treatment you're giving the victim in its specifics. Finally, you record victim outcomes.
(Any vaguely ethical researcher would pick non-human animals with a similar mass-to-surface-area ratio to humans, of course, even if they were spurning modern ethical traditions. Rat studies are more likely to get approved, but rats have a lot more surface area for their mass, so they change temperature faster. This can alter your results significantly.)
The Nazis didn't bother with any of that. They just chucked people in cold water (how cold?), left them for a while (how long?), and tried warming them up with various means. They didn't even record survival rates. They weren't concerned with spending lives to advance human knowledge, which would still be horrific. They just wanted to get paid to torture people in various ways.
Even if the ethical considerations weren't at play, any modern researcher trying to analyze the data they recorded
would give it up for useless.
Even their non-invasive science was suspect. Their anthropological and genetic reports had to support the ideology of Germanic superiority. However, since a lot of that data was collected with a purpose other than torture, there was actual science to glean from it, even though it had to be independently confirmed.
Meanwhile, they dealt blows to medical science in other areas. In the early 1900s, Germany was
the place to go to get transgender medical care. First sex reassignment surgeries. First top surgeries. First hormone therapies. First attempted cross-sex reproductive organ transplants. The Nazis destroyed all that data. You know the images of Nazis burning books -- that's at least some of what they were burning.
