True story, I stuck some of his preserved birds in a freezer once (regular insect prevention).
Who is that, and why is that, your night ask. Well, here's the relevant wikipedia quote. Reference numbers maintained, because damn, that's a lot of them.
The success of Birds of America has been marred by numerous accusations of plagiarism, scientific fraud, and deliberate manipulation of the primary record.[33][68][103][66][104][105] Research has uncovered that Audubon falsified (and fabricated) scientific data,[58][106] published fraudulent data and images in scientific journals and commercial books,[33][68][103][105] invented new species to impress potential subscribers,[68] and to "prank" rivals,[58][106] and most likely stole the holotype specimen of Harris's hawk (Parabuteo unicinctus harrisi) before pretending not to know its collector, who was one of his subscribers.[107] He failed to credit work by Joseph Mason, prompting a series of articles in 1835 by critic John Neal questioning Audubon's honesty and trustworthiness.[108] Audubon also repeatedly lied about the details of his autobiography, including the place and circumstances of his birth.[109][110] His diaries, which might have cleared up some of these issues, were destroyed by his granddaughter, who published a doctored version that realigned the "primary" record with some of his false narratives.[105]
