Harry Ralton, born Karl-Heinz Rosenthal on May 2, 1907, in Breslau (now Wrocław), was a German composer, pianist, and author known for his contributions to light music during the interwar period. He was the son of Salo, a wholesale merchant, and Margot. Demonstrating significant musical talent from a young age, Ralton pursued a career in music initially in Silesia and later in Berlin from 1931. In 1933, he adopted the professional name Harry Ralton. His compositions were performed by notable figures of the time, including Richard Tauber.

The ascent of the Nazi regime severely restricted his professional opportunities in Germany. Ralton was imprisoned in Buchenwald before escaping to Britain, arriving in Harlow on August 28, 1939. Tragically, his mother was unable to leave Germany and was murdered in the Holocaust. In Britain, Ralton initially resided at the Money Hill Hotel in Rickmansworth, where he formed a friendship and musical partnership with pianist John Wallington. He also met May Reeve, who became his benefactor, and Alfred Kalmus, an Austrian with strong connections to the Viennese music scene, who offered him support and accommodation in Wembley after Ralton had to leave Rickmansworth.

Ralton's work included dance and entertainment music, with pieces such as "The Dolly Brothers" (Foxtrot), "Baby, du hast dich verändert" (Foxtrot, lyrics by Fritz Rotter), and "Eine kleine Liebelei" (Boston, lyrics by Fritz Rotter). His life and career were marked by the challenges of exile and the impact of the Holocaust on his family. Harry Ralton passed away on September 30, 2018.
