“The 28 documents include detailed blueprints of prisoner barracks, gas chambers marked clearly Gaskammer (Gas chamber) in a Gothic-inspired font”
wasn’t *all* printed german in similar fonts up until fairly recently, as in the last few decades?
No. The Gothic style font became a lot less common after WWII. The Gothic style font was much more common in printed documents before the 20th century, while the use of a Latin font became more common throughout the 20th century. So blueprints from the Nazi period could have used a Gothic or a Latin font.
These blueprints should be reproduced and widely published because as time goes by more and more wicked people will try to convince the world that the Holocaust never happened. It is interesting that some kooks who have all sorts of weird conspiracy theories about everything are the same people who try to claim that the well-documented crimes of the Nazi period never happened!
Since the late 18th century, Fraktur began to be replaced by antiqua as a symbol of the classicist age and emerging cosmopolitanism. The debate surrounding this move is known as the Antiqua-Fraktur dispute.When I learned German in HS in the early 60's we had to learn to read Fraktur, as well as modern script because of the fact that so many books were still around which were printed in Fraktur.However, the shift mostly affected scientific writing, while most belletristic literature and newspapers continued to be printed in broken fonts. This radically changed when on January 3, 1941 Martin Bormann issued a circular letter to all public offices which declared Fraktur (and its corollary, the Sütterlin-based handwriting) to be Judenlettern (Jewish letters) and prohibited further use. It has been speculated that the régime had realized that Fraktur would inhibit communication in the territories occupied during World War II.
Fraktur saw a short resurgence after the War, but quickly disappeared in a Germany keen on modernising its appearance.
