Wilhelm Kampin (1885 - 1951) initially did an apprenticeship in the glassworks under his father in Easter Castle near Oldenburg. At the same time he took lessons from Gerhard Bakenhus. His artistic talent was noticed by the head of the glassworks and commissioned some paintings for new ships of the Oldenburg-Portuguese steamship shipping company, which was also in charge of this. Kempin then traveled by ship to Portugal to study. After these initial successes, he began his studies at the art college in Weimar in 1911 and became a master student of Max Thedy. During the First World War he returned to Oldenburg, where he lived until his death and made the landscape around Oldenburg his subject in painting.
The birch trunk shows its interest in the details of its landscapes. Kempin paints the light and dark sides of the trunk with a quick brush. The unique white flaked bark and knotholes make the trunk so fascinating. The unfinished nature of the study has an additional appeal.
