http://viaf.org/viaf/16536304 has 1981 death as do many others around the internet. I do not know what evidence they have and I don't know what evidence you have :) (If it is already linked to in the article, I apologize, I am translating it by the skin of my teeth. Otherwise- is there an obituary notice somewhere?) Thank you and apologies, but especially thanks in advance. Schissel (обс.) 13:14, 30 апреля 2017 (UTC)
