Various, Notes and Queries, Number 180, April 9…
“ There is a term now coming a little into use, which is I believe of pure Irish origin, namely, old fogie. Indeed, I have heard it used rather disrespectfully of those mature old warriors, whom it pleases the wisdom of our government to send out in the command of our fleets and armies. The word, as I said, is of Irish, or rather of Dublin birth. The old fogies are the inmates of the Royal or Old Men's Hospital, the Irish Chelsea. I think, then, that it must be plain to every one that the term is nothing more than a good-humoured corruption or diminutive of old folks. ”
