Yep, the term was known when I became KN6DGW in 1953, but somehow no one 
cared.  Standing waves were sort of benign, you ran your transmission 
line [often 300 ohm open-wire, or TV twinlead] to the 2 or 3 turn link 
and adjusted it inwards until your TX was "loaded" to rated input 
power.  Standing waves formed the basis of "Lecher Lines" used to 
measure frequency [well ... wavelength] generally for VHF and above.  
Standing waves just didn't create the heartburn that they seem to 
today.  Granted, today's TX are comfortable with 50 ohms and not much 
else but that's just impedance matching networks.
