This page is a fairly free translation, so please let me know if you disagree with anything. I wasn't sure what to do with the "Works" section, where obviously the titles of what he published during his lifetime are in German. I have added translations of the titles for the benefit of the reader. I have not translated the final item as it's most confusing; it looks to be a near-exact copy of the previous publication but with a few more illustrations and a publication-city marked in the German version with an exclamation mark - presumably as it's a different city, and not where Töpfer lived and published. I have left this as it was in the German version, but replaced the exclamation mark with "sic" to indicate that the location is what it is.
The page has only a single reference; it would undoubtedly benefit from more, for example if someone has access to Grove. I can probably find more if necessary. I haven't, for example, provided a reference that Töpfer's publications on pipe-scaling are still of enormous relevance to organ literature today, as there's a reference in the linked Wikipedia page, but I could.
