> I heard that Bob Morris was asked for his initials, he said “rm”, they insisted on a middle initial, which he didn’t have, so he supplied “h”, hence “rhm”.

True in principle, but when it happened and who "they" were, is lore
beyond my ken. I presume it was before he joined Bell Labs. At the
labs, interoffice communications typically used initials, so the 
DMR, JFO, RHM convention was well established. Only the affectation
of lower-case only was new--and that was the fault of unicase Model
33. Who wanted to SHOUT EVERYTHING they wrote, or litter it with escapes?
