As for his given name, although the spelling "Edmund" is quite common, "Edmond" is what Halley himself used, according to a 1902 article,The Times (London) Notes and Queries No. 254, 8 November 1902 p.36 though a 2007 International Comet Quarterly article disputes this, commenting that in his published works, he used "Edmund" 22 times and "Edmond" only 3 times, with several other variations used as well, such as the Latinised "Edmundus". Much of the debate stems from the fact that, in Halley's own time, English spelling conventions were not yet standardised, and so he himself used multiple spellings.
