"Heinrich Rehkemper (born 1894, died 1949) was a German baritone singer whose repertoire was in opera and Lieder, and whose career was principally in Germany between the First and Second World War. The greater part of his career was spent as leading baritone at the Munich opera house.
Rehkemper studied at Düsseldorf, and made his debut in opera in Die Faschingsfee by Emmerich Kálmán in 1919, at Coburg. Over the next two years he also sang there in Nicolai's Die lustigen Weiber von Windsor, in Lohengrin, Carmen and Cavalleria rusticana. From 1921 to 1924 he was engaged at the Stuttgart opera, and during the first three years of this time he sang over forty different lead roles. At the end of three years he broke his contract, and was therefore legally forbidden to make stage appearances for the final year. In that time he began to develop his concert repertoire and persona. He gave recitals of songs by Schubert, Schumann, Wolf and Mahler: he also took the baritone solo role in a performance of Beethoven's 9th Symphony, and in J. S. Bach's St. John Passion in a performance at Vienna." - (en.wikipedia.org 24.03.2022)
