Hello, I'm Materialscientist. I noticed that you made a change to an article, Wilhelm August Rieder, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Materialscientist (talk) 10:17, 29 May 2020 (UTC)
 * If this is a shared IP address, and you did not make the edits referred to above, consider creating an account for yourself or logging in with an existing account so that you can avoid further irrelevant notices.

Please do not add or significantly change content without citing verifiable and reliable sources. Before making any potentially controversial edits, it is recommended that you discuss them first on the article's talk page. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Materialscientist (talk) 10:30, 29 May 2020 (UTC)
 * I've put back thje edits you made the second time because they did cite sources in the style of the rest of the article. The problem is that most Wikipedia articles these days cite their sources online;see Help:Referencing for beginners for more information about that. It'd also be much better if you created an account, which has several benefits, including making it less likely that your edits will be reverted as vandalism. Graham 87 14:56, 29 May 2020 (UTC)
