[1] With his Strasbourg friend Jules Berninger (also his future brother-in-law), Gustave Krafft studied in Stuttgart in 1878–79, then at the École des beaux-arts in Paris from 1881 to 1886 in the atelier of Jean-Louis Pascal.

Several years later, after moving back to Strasbourg (then part of the German Empire), he became one of the foremost practitioners of Art Nouveau (known as Jugendstil in German-speaking countries).

[2] Gustave Krafft exhibited his art at the salon of the Revue alsacienne illustrée in 1905, at the Galerie Bader-Nottin at 23 rue de la Nuée-Bleue with Théodore Haas, Léon Hornecker, Albert Koerttgé, Henri Loux, Lothar von Seebach, Charles Spindler, and Gustave Stoskopf.

In 1921, after Alsace was returned to France in 1919, Krafft was named professor at the new École régionale d´architecture de Strasbourg and was appointed to the Ordre des Palmes académiques.

Goehrs directed the Strasbourg branch of the Evangelische Gesellschaft für Deutschland (German Evangelical Society) from 1881 to 1919.
