No. It was Nietzsche's sister's twisting of what he wrote that may have inspired Hitler. She was married to a devout racist, may have already been one herself. After N. died, she took over as editor, and owner, of his works and bent his writings to her needs.
I think mistranslations, misreadings, and worse yet, misinterpretations not in any way based on any act of reading of Neitzsche can inspire a lot of hatred. The man had his issues, to be sure, but i've found that those who quote him with the intention of equating atheists with monsters, quote him very selectively.
Perhaps Hitler thought that, but I doubt if he had ever read him. Neitzsche's concept of the "ubermensch" is really rooted in individual superiority and he never goes into race. Zarathustra was proclaiming the ubermensch as rising above the men around him, finding his truth in himself and not being tied to the traditional morality of the group. There's no racial component to it at all. In fact, it was antithetical to "racial" superiority as that's just another group which a true ubermensch would rise above.
Much of the alleged inspiration came from The Will to Power, which was not actually written by Nietzche, but is a book of notes drawn from the literary remains of the philosopher Friedrich Nietzsche by his sister Elisabeth Förster-Nietzsche and Peter Gast in order to generate some income after Nietzche's death. It was primarily Heinrich Himmler who used these notes, often out of context, to support his Nazi propaganda. Nietzche, once greatly admired, has suffered a bad reputation ever since.
NO not exactly.
Hitler was an admirer of Nietzsche writings, but after the philosophers death, Nietzsche's money hungry sister who was on friendly terms with "Der Phooey" published and gifted to Hitler a series of writings of her brothers older writings (most later contradicted by actual published works) that Nietzsche had long since dismissed as the "rantings of youth"
These works were Hitler's professed inspiration and passed off by Hitler as "new" writings by Nietzsche, the last thoughts of a genius, when they were no such thing, but rather inferior ideas rejected and dismissed decades before.
