Yuri Veniaminovich Geronimus life data
Hi Roundabout. Some while ago, you added a death date to Yuri Veniaminovich Geronimus' name. As you have probably seen, until we have articles about them I am trying to at least compile some notes and "mini-bios" for the contributors to the book Gradshteyn and Ryzhik. However, I was unable to find any more specific info in regard to the various Russian authors. Do you have a reliable source for Yuri Veniaminovich Geronimus' death date or any other info about him? Or any more info about the other Russian authors? --Matthiaspaul (talk) 14:10, 7 July 2020 (UTC)
