I have a number of old chess books published by R.H.M. Press. I am curious as to whether "R.H.M." are the initials of something or someone, and if so, what?
As I understand it, R.H.M. Press was the brainchild of Sidney Fried, and Burt Hochberg was the chief editor of many of the books. Unfortunately, neither of them is still alive. I found a short article by Hochberg in the Summer 2000 issue of Publishing Research Quarterly entitled "An imperfect visionary," which gives some interesting historical information about R.H.M. Press, but no hint of what R.H.M. might stand for, if anything.
None of the possibilities listed by The Free Dictionary looks plausible to me.
