Was it coined in 1915 or 1916? By Charles N. Chadbourn or Charles N.  
Chadbourne? Could OED verify the spelling of his name?

the National Association adopt a professional title to be conferred upon its  
members which they shall use to distinguish them from outsiders. That this 
title  be copyrighted and defended by the National Association against misuse...

syllable). 1922 _S.  LEWIS_ (http://dictionary.oed.com/help/bib/oed2-l.h
