The article says he was born in 1869. I am unable to access the Ancetry documents to see if that agrees. I have found this [1] which is a primary source. The things is, nothing we have on him would not work with the 1896 birth, but nothing clearly goes against the 1869 birth. I am beginning to think that 1896 is probalby more likely, but the one reliable source I was able to access here, and [2] which seems to be on the same person does not mention a birth date. I am also beginning to wonder if we have enough sourcing to be sure there is only one academic from the mid-20th century named Paul Kosok.John Pack Lambert (talk) 20:39, 1 July 2022 (UTC)[reply]
