This one needs thorough checking for neutrality and verifiability, seems to have lots of padding and puffery. Sources like this should not be used to support claims about notability and being the first this or that, while sources like this or this don't even seem to mention Sargent at all. Same goes for this, while this may or may not include Sargent, but as no one independent has remarked upon his role in this, it shouldn't be included. Fram ( talk) 12:55, 14 February 2024 (UTC) reply
