Ludwig Schmidseder (24 August 1904, in Passau – 21 June 1971, in Munich) was a German composer and pianist known for his contributions to the genre of "Light Muse." Despite initially training as a banker to satisfy his father's wishes, Schmidseder pursued his passion for music by taking piano lessons in secret and later studying at the Munich Conservatorium. In 1926, he moved to South America, where he started as a dishwasher and eventually became an entertainer and pianist in a trio on ocean cruises.

By 1930, Schmidseder was working in Berlin, where he composed film music, created operettas, and wrote over 500 songs, many of which became popular hits. Notably, his operetta "Die Oder Keine" was performed more than 600 times. He served as the house composer at the Berlin Metropol-Theatre and joined the NSDAP on 1 May 1933. After World War II, Schmidseder continued to compose film music and appeared in films. He also gained fame as a TV cook and published a cookbook. Some of his notable operettas include "Melodie der Nacht," "Frauen im Metropol," and "Abschiedswalzer." His Schlager hits include "Gitarren spielt auf" and "Ich trink den Wein nicht gern allein." His film credits include "The Country Schoolmaster" and "The Lady in Black."
