A stained glass window of a Latin square (https://en.wikipedia.org/wiki/Sir_Ronald_Fisher_window) will be removed from Cambridge U. (https://www.theguardian.com/education/2020/jun/27/cambridge-gonville-caius-college-eugenicist-window-ronald-fisher) because it honors prominent eugenicist R. A. Fisher (https://en.wikipedia.org/wiki/Ronald_Fisher).
The window visualizes a nice piece of mathematics, with a long history that surprisingly originates in Korea (predating Euler) but in context among windows celebrating Cambridge luminaries it could not be separated from Fisher's racist history, so it's sad but I think it's the right decision.
