"(Philipp) Eduard Devrient (11 August 1801 – 4 October 1877) was a German baritone, librettist, playwright, actor, theatre director, and theatre reformer and historian.
Devrient came from a theatrical family. His uncle was Ludwig Devrient and his brother Karl was the first husband of Wilhelmine Schröder-Devrient.
He was born and studied in Berlin and performed in a number of German opera houses between 1819 and 1834, when he lost his singing voice and turned his attention to writing and acting. From 1844-6 he worked in Dresden as actor/director, and he directed the Hoftheater in Karlsruhe from 1852 until his retirement in 1870." - (en.wikipedia.org 12.07.2020)
