An interesting claim, but as they say on Wikipedia, . I’ve been searching at Google Books and can find no backup for it; on page 460 of 5000 Jahre Geometrie: Geschichte, Kulturen, Menschen, for instance, it just says “die nach ihm benannte „Flasche” (auch als „Schlauch” bezeichnet)” ["the ‘bottle’ named after him, also called a ‘tube’], with no mention of this supposed distortion via English. Until I see some proof, I’m voting for folk etymology.
Edit: I have deleted the sentence from the Wikipedia article. It’s been unreferenced for three years, and that’s long enough.
