Hello, I'm Dewritech. I noticed that you added or changed content in an article, Robert Koch, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you.  Dewritech (talk)  13:07, 20 April 2022 (UTC)

Please do not add or change content, as you did at George Miller Sternberg, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you.  Dewritech (talk)  13:08, 20 April 2022 (UTC)
