Peter Igelhoff, born Rudolf August Ordnung on July 22, 1904, in Vienna, Austria, was a prominent Austrian pianist, light music and film composer, arranger, and entertainer. He adopted his mother's maiden name, Igelhoff, upon deciding to pursue a career in light entertainment. Igelhoff began his career as a jazz pianist in bars and later refined his style by studying in London during the early 1930s. He subsequently moved to Amsterdam and then to Berlin in 1935, where he became heavily involved in film and recording studio work, collaborating with fellow composer-pianist Georg Haentzschel.

Igelhoff's light songs were commercially successful, and his career initially remained unaffected by the outbreak of World War II in 1939. However, the National Socialists eventually banned his music for being too American in style. Despite his style falling slightly out of fashion by the late 1940s, Igelhoff remained active in his field until the end of his life and was honored with a professorship for his contributions to music.

Known for his exceptional piano skills and concert technique, Igelhoff often accompanied his light tenor voice and virtuoso whistling in his performances. He composed over 1,000 songs, including notable works such as "Wir machen Musik," "Der Onkel Doktor hat gesagt," and "Delirium." His music continues to charm and surprise new generations, thanks to his extensive recordings. Peter Igelhoff passed away on April 8, 1978, in Bad Reichenhall, Germany.
