From Wikipedia:
Ferdinand Gumbert (* 22 April 1818 in Berlin, Kingdom of Prussia; † 6 April 1896 in Berlin, German Empire) was a German composer, singing teacher and music critic. Initially a singing teacher, he began a stage career as a baritone in 1839.
After an engagement of several years at the Cologne Stadttheater (1840-42), he resigned from stage work in favour of composition on the advice of Kapellmeister Conradin Kreutzer. In addition to his activities as a singing teacher and song composer, he worked from 1881 as a music consultant for the Täglichen Rundschau, as well as for the Neue Berliner Musikzeitung in Berlin.
His singing students included Karl Formes and Rosa Le Seur. Gumbert translated numerous libretti from French into German.
Ferdinand Gumbert came from a Mosaic family and was not married.
