All the research was destroyed? Why would that happen. I mean if the Nazis were defeated, then why aren't the experiments openly revealed.
The scientists themselves managed to destroy or hide some of their research at the end of the war as it could otherwise have been used against them as evidence that they committed war crimes.
Much research did survive but it was often not discussed in scientific circles because of the embarrassment caused by the scientific community by some of its members having been involved in experiments where such terrible means were used to achieve the ends. Understandably, nobody wanted to be associated with the Nazis after the war was over.
Many former Nazi scientists continued to work. Some concealed their wartime activities, e.g. by destroying evidence, but in many cases the Allies knew of their crimes but ignored them in order to be able to make use of their scientific expertise There was competition between the US and Britain on one side and the USSR on the other for German scientific expertise. The most well-known example of this is Operation Paperclip, by which the US invited many German scientists with unsavory backgrounds to work in the US. The best-known such person was Wernher von Braun, who designed rockets for the Nazis during the war and later designed the rockets that put Americans on the moon. He is widely considered to be the greatest rocket scientist of all time. His wartime Nazi background including the use of forced labor from concentration camps in the construction of his V-2 rockets was concealed until after his death in the 1970s.
One of American satirical singer-songwriter Tom Lehrer's most famous songs was about Dr. von Braun:
Gather round while I sing you of Wernher von Braun
A man whose allegiance is ruled by expedience
Call him a Nazi, he won't even frown
"Ha, Nazi schmazi," says Wernher von Braun
Don't say that he's hypocritical
Say rather that he's apolitical
"Once the rockets are up, who cares where they come down
That's not my department," says Wernher von Braun
Some have harsh words for this man of renown
But some think our attitude should be one of gratitude
Like the widows and cripples in old London town
Who owe their large pensions to Wernher von Braun
You too may be a big hero
Once you've learned to count backwards to zero
"In German oder English I know how to count down
Und I'm learning Chinese," says Wernher von BraunMagnus wrote:
I still wonder what they Nazis were selecting for with eye color and hair color. It's hard to believe they just wanted to breed for looks. I think they were experimenting with Aspergers, trying to refine it or something.
This is very unlikely.
Nazi eugenics were simply based on the pseudo-scientific idea that people of Northern European descent (who happen to be more likely to have light hair and blue eyes) were superior in every way (intelligence, morality, culture, physical strength, etc.) to other people. This concept was considered quite respectable in much of the world (the US was probably the other leader in the "science" of "racial purity") until after World War II was over. The Nazis, having taken it to its horrific logical extreme, destroyed its social acceptability.
