The two best-known of Hindemith's fellow pupils are above all Hans Rosbaud, who later committed himself in exemplary fashion to New Music during the 1950s as Music Director of the Southwest Radio Orchestra in Baden-Baden, and Werner Wehrli, a composer from Aarau who was a scholarship holder of Hoch's Conservatory at the same time as Hindemith.
Hindemith's fellow pupils in the Sekles class included Max Kowalski and Johann Friedrich Hoff. Max Kowalski, whose main professional was as a lawyer, composed lieder including settings of poems from Guiraud's «Pierrot lunaire» that were often performed during the 1920s. Johann Friedrich Hoff was among the «most brilliant personalities in Frankfurt's musical life of the recent past» (P. Cahn). He wrote a number of lieder cycles and chamber works. The string quartet «Breugnon Suite» by Hoff was performed by Hindemith with the Amar Quartet in Donaueschingen in 1923.
Other pupils of Sekles were Theodor W. Adorno and Ottmar Gerster.
