Hello, I'm Materialscientist. I noticed that you made an edit concerning content related to a living (or recently deceased) person, but you didn't support your changes with a citation to a reliable source, so I removed it. 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! Materialscientist (talk) 01:19, 5 September 2017 (UTC)
