Talk:Vladimir Markovnikov

Birth date
The article has two birth dates of Markovnikov, perhaps by mistake:
 * December 22, 1838 and December 25, 1837

Which one is correct? If the birth date is unclear and both birth dates have been mentioned by multiple sources, then I think those sources available at the Russian Wikipedia page Марковников, Владимир Васильевич. &mdash; CrafterNova [ TALK ]  [ CONT ] 10:36, 14 June 2022 (UTC)
