Talk:Bernhard Eduardovich Petri

Self published sources claim
I wrote this article based upon Sirina 1999 which is the primary biography on Petri. There are no self published sources used so I removed that tag. I'll add more sources in the coming weeks but this is already significantly more informative than the Russian edition. Voltaire&#39;s Vaquero (talk) 16:15, 13 March 2022 (UTC)
