To add a little to post by Jim Dixon:
Ernst Neubach was known primarily as a screenwriter; perhaps best known was the 1956 "Die Fischern vom Bodensee," which was given 'art' theatre showing in America.
Ralph Maria Siegel, b. 1911, was a songwriter, also writing music for films. He did the score for the 1955 English film "I Am a Camera," the script of which received poor reviews in New York.

The German text of the song in the DT is OK, except umlauts and 'double-ess' S#223; are not printed. See http://ingeb.org/Lieder/imhimmeg.html for accurate transcription.
