After this, between 1924 and 1925 Gustav Seitz studied with the sculptor Georg Schreyögg at the State Arts College ("Landeskunstschule") in Karlsruhe.
[2] From 1925 till 1929 he was studying under Ludwig Gies at the Berlin University of the Arts (at that time identified as the "Vereinigte Staatsschulen für Freie und Angewandte Kunst").
He was also able to travel, first, in 1926, to Italy where he was much influenced by Etruscan terracotta antiquities, and later in much of Europe, notably in Paris where he had been able to visit Charles Despiau during a study trip in 1929.
In 1949 he was an early recipient of the National Prize of East Germany (Class 3) for his "Victims of Fascism" ("Opfer des Faschismus") memorial in Berlin's Weissensee quarter.
[4] In 1950 he succeeded Edwin Scharff at the Fine Arts Academy in Hamburg, triggering a widespread "east-west" debate at the time.
[4] Seitz's sculptural legacy includes a number of female nudes with a particular focus on a range of differently posed squatting figures.
