"Robert Gilbert (born Robert David Winterfeld) (29 September 1899, Hamburg, Germany – 20 March 1978, Minusio, Switzerland) was a German composer of light music, lyricist, singer, and actor. His father was Max Winterfeld, a composer and conductor who went by the pen name of Jean Gilbert. His brother was Henry Winterfeld, an author of children´s books. Sometimes described as a "divided author", his early depression-era poem "Stempellied" about living on the dole was set to music by Hanns Eisler. But "Am Sonntag will mein Süsser mit mir segeln gehen" ("On Sunday I´ll go sailing with my Sweetheart") and "Das gibt´s nur einmal" ("It Happens Only Once"), became his better known work." - (en.wikipedia.org 27.10.2019)
