She was born in Mährisch-Ostrau in Austria-Hungary (today Ostrava in the Czech Republic), as Lore Schirmer. She studied history, German literature and philosophy in Berlin and Vienna. In Berlin she met Kay Lorentz, who became her husband in 1944.
Until 1983 Lore and Kay Lorentz were not only the heads of the Kommödchen, they were part of the ensemble at the same time. From 1983, she started with solo programs. One of her most famous programs consisted exclusively of texts written by Heinrich Heine; even though he had written them more than a century before Lorentz' program was performed, they all referred to current topics.
She received several prizes:
- 1981: Ehrenpreis des Deutschen Kleinkunstpreises
- 1986: Staatspreis des Landes Nordrhein-Westfalen
- 1989: Großer Kulturpreis der Sparkassenstiftung des Rheinischen Sparkassen- und Giroverbandes
Kay and Lore Lorentz rejected the Bundesverdienstkreuz (Federal Cross of Merit) in 1976.
She died in 1994 in Düsseldorf of pneumonia.
