More than once: even after knowing the full title from a previous read but glancing and reading it as "Hitler" anyway multiple times. I think it's a result from the uppercase first letter on each word: it's common to read Hitler with uppercase h but not Hitters with uppercase h. And as word recognition is a function of the peripheral letters of the word it gives a cognitive mishap.
Edit: This could very well be a textbook example on why not use uppercase first letters when not needed on UIs.
