In 1920, when these arrangements foundered, Gropius invited Max Krehan to move to Weimar and join the Bauhaus staff.
Krehan refused to leave his Dornburg pottery, but he did agree to work with students at that location (about fifteen miles from Weimar).
Among the students there that year were Marguerite Wildenhain, Gertrud Coja, Lydia Foucar, Johannes Driesch, Theodor Bogler and Otto Lindig.
Shortly before her death, Wildenhain (Krehan's student) gave to one of her students and close associates, American potter Dean Schwarz, a small, handwritten German diary, with an inscription on the title page that reads Dem letzen Töpfere seines Stammes (To the Last Potter of His Lineage).
Years later, when translated, the diary was found to consist of letter-like entries from Wildenhain to Krehan, written after his death, from October 1925 to May 1926.
