Gordon Kent was (is, I suppose) two people, my son - Christian Cameron, author of TYRANT and WASHINGTON AND CASEAR and other books - and me. The reason for the pseudonym was the obvious one that two names on a cover were not thought as good as one. And of course the one needed to be anglo and male; my suggestion of Max Cohen got nowhere, as did several dozen others we trotted by the publisher. Eventually, we settled on Gordon Kent: Gordon was my father's name, my son's middle name; Kent, oh, well.
We wrote eight novels - the Alan Craik books - under this pseudonym. The books were about the air side of the US Navy, mostly about intelligence, but with a lot of derring-do that real intel officers never get to play at.
