Feb 15, 2022 at 17:56 comment added Timothy Chow There's some interesting historical information here about the related term "circle-squarer" which apparently goes back to ancient times.
Feb 15, 2022 at 14:54 comment added Paul Taylor Wiktionary says that crackpot was originally crack-pate and pate is definitely an archaic word for head.
Feb 15, 2022 at 12:35 comment added Gerald Edgar I think the question belongs in hsm.stackexchange.com
Feb 15, 2022 at 11:29 comment added Manfred Weis @StefanKohl that's true, but I can't think up a nice translation of crackpottery to German that uses the same "image" of a cracked pot as a noun that could be used for cranky maths in German.
Feb 15, 2022 at 10:37 comment added Stefan Kohl @ManfredWeis The term exists quite literally in the same meaning also in (very colloquial!) German language -- einen Sprung in der Schüssel haben.
Feb 15, 2022 at 10:18 comment added Brendan McKay Augustus de Morgan's 1872 book "A Budget of Paradoxes" refers to a persistent circle-squarer as a "crack man". I haven't heard that variation before.
Feb 15, 2022 at 9:18 comment added Jukka Kohonen (But to clarify: Halmos not really referring to crackpottery in math, rather in engineering and physics.)
Feb 15, 2022 at 8:28 comment added Jukka Kohonen Not sure if it counts as a "math paper", but Paul Halmos mentioned crackpot inventors and crank experiments in his 1958 piece "Innovation in mathematics" in Scientific American.
Feb 15, 2022 at 6:49 comment added Manfred Weis @BrendanMcKay that explanations further clarifies that it doesn't relate to pottery in a literal meaning. Thanks for elucidating that to the non native English speakers.

Feb 15, 2022 at 5:11 comment added Brendan McKay "Pot" is an old colloquialism for "head", so a "crackpot" is someone with a cracked head. There are plenty of examples from the 1800s. An older version, going back at least to the 16th century, is "crackbrain". None of this answers the mathematical question.
Feb 15, 2022 at 4:48 comment added Nik Weaver I rather like this question, but yeah, it seems pretty far off topic.
