- 13:5613:56, 27 April 2022 diff hist +4 m Mahlon Loomis All edits were made to the next-to-the-last sentence of the first paragraph, for spacing, spelling, and punctuation. Because a) this sentence is riddled by inconsistent mistakes, b) its insertion appears to self-confirm a claim (that Loomis was clearly the first), and c) it contains the only obvious evidence of my concern, I'm led to believe that a sole editor has inserted that sentence out of some sort of bias. But I left it in, to give the editor the benefit of the doubt.
