The following biographical information has been provided by David Kwiat, researcher.

Curt Lahs was born in Dusseldorf in 1893. In 1919 he had his first group show in the Galerie Flechtheim, Dusseldorf. In 1921 he became a member of the influential art collective, "Junge Rhineland", whose members included Johanna Ey and Peter Jurgen. He subsequently exhibited at Mutter Ey.

Beginning in 1930, and up until his teaching credentials were taken away by the Nazis as a result of his "anti-fascist" activity, Lahs taught art at the State Art School in Berlin. From 1933 to 1943, Lahs had numerous shows in France, Italy, and Yugoslavia, and in 1945 he participated in two well known shows at Galerie Gerd Rosen and Galerie Bremer.

From 1947 on, Lahs taught art at the University of Halle, and later at the School for Art in Berlin (Hochschule fur Bildende Kunste in Berlin). He was the recipient of the Stahl und Eisen (Stell and Iron) Kunstpreis (Artprize) in 1952, Dusseldorf, and received the Artprize of the City of Berlin (Kunstpreis der Stadt Berlin) in 1954.

Lahs' career began with the founding of the artist group Das Junge Rheinland and a collective exhibition at the Galerie Flechtheim, Düsseldorf in 1919.

Two years later he became a member of the group Das Junge Rheinland, and he also had an exhibition at “Mutter Ey”. In 1937, as part of the "Degenerate Art" campaign, his works were requisitioned from museums and some were destroyed; the artist had to emigrate. In 1946 and 1947 he exhibited in the Berlin galleries Gerd Rosen and Bremer.
