Hello, I'm David Eppstein. I noticed that you made an edit concerning content related to a living (or recently deceased) person   on Pierre Rosenstiehl, but you didn't support your changes with a citation to a reliable source. It's been removed and archived in the page history for now. Wikipedia has a very strict policy concerning how we write about living people, so please help us keep such articles accurate and clear. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you! —David Eppstein (talk) 21:25, 30 October 2020 (UTC)
