Lexicographer

Lex`i*cog"ra*pher (- ĭ*kŏg"rȧ*fẽr), n. [Gr. lexikogra`fos; lexiko`n dictionary + gra`fein to write: cf. F. lexicographe. See Lexicon.] The author or compiler of a lexicon or dictionary.

Every other author may aspire to praise; the lexicographer can only hope to escape reproach; and even this negative recompense has been yet granted to very few.
