Gotthold Ephraim Lessing (German: [ˈlɛsɪŋ]; 22 January 1729 – 15 February 1781) was a German writer, philosopher, dramatist, publicist and art critic, and one of the most outstanding representatives of the Enlightenment era. His plays and theoretical writings substantially influenced the development of German literature. He is widely considered by theatre historians to be the first dramaturg in his role at Abel Seyler's Hamburg National Theatre.
