"Herbert Ihering (also sometimes Herbert Jhering: 29 February 1888 - 15 January 1977) was seen by many contemporaries as one of the leading German theatre critics during and after the Weimar years.
He was one of the earliest supporters in print of Bertolt Brecht, which formed one basis for a long period of very public disagreement - which sometimes degenerating into journalistic feuding - with Alfred Kerr. Later Ihering incurred the enmity of the dramatist Klaus Mann, who was widely believed to have incorporated Ihering in his novel "Mephisto" as the opportunistic theatre critic and gossip Dr Ihrig (in later editions Dr.Radig)." - (en.wikipedia.org 01.02.2020)
