Carl Wendolin Scherer was a Swiss painter and commercial artist.

Carl Scherer completed an apprenticeship as a sign and decorative painter in Basel from 1904 to 1906. After that, he traveled to Germany several times before the outbreak of World War I. An avowed socialist, he designed numerous posters for the labor movement and also served as editor of the short-lived magazine Werden – Monatsblätter für sozialistische Kultur und Arbeit (becoming – monthly sheets for socialist culture and labor) in 1920/21.

In Switzerland, Scherer made a name for himself primarily as a designer of political posters. He made his graphic design skills available to the Social Democrats, and from the mid-1920s also to the Free Democrats and the Communists, who had been organized in Switzerland in the Party of Labor since 1944. He also created posters for the Swiss Mustermesse trade fair. As a painter, Scherer devoted himself primarily to landscape painting and still lifes.

Carl Scherer died in Zurich, where he had been living since 1944, in 1953.
