dramaturge

A dramaturge or dramaturg (from Ancient Greek δραματουργός – dramatourgós) is a literary adviser or editor in a theatre, opera, or film company who researches, selects, adapts, edits, and interprets scripts, libretti, texts, and printed programmes (or helps others with these tasks), consults authors, and does public relations work. Its modern-day function was originated by the innovations of Gotthold Ephraim Lessing, an 18th-century German playwright, philosopher, and theatre theorist.
