The story (in "software superheroes", thoroughly good read) is that the British computer scientist George Coulourais, was visiting Bell Labs and met with Ken Thompson. Ken was editing some of the unix code base using a 'ed'- with no reference printout, no display, just typing from memory. George was simply astounded and so christened his own editor (which used raw input to allow line by line editing) 'em' or Editor for Mortals

Subsequently he gave the code to Bill Joy who turned it into ex and then vi and at some point even Ken Thompson probably used it.

"Our" history (as coders) is short and surprisingly oral, but still has gods in it and messengers from the gods bringing down the fruits of their wisdom.
