Deletion of John Dwyer (mathematician)

Comment: I don't think https://www.theiet.org/membership/becoming-a-member/join-the-iet/fellow-membership/ Fellow IET is enough for #C3, as it's more or less "employed in a managerial role and member in good standing for five years" rather than a more selective honor (Honorary Fellowship, a higher grade of membership, might be). I can't find the citations that would allow him to pass #C1. So the only possible remaining source of notability would be as a textbook author (#C4 and ). But his books appear to either be self-published or from a very minor publisher (I can't tell which) and I can find neither published reviews of them nor evidence that they have been assigned as textbooks in any major institution of higher learning. So I can't find evidence of notability that way either
