Hello, I'm Serols. I noticed that you made a change to an article, Katherine Johnson, 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. Serols (talk) 13:51, 27 July 2021 (UTC)
