Karl Kellermann was a German painter born in 1881 whose career centered on landscape painting, particularly scenes of the Bodensee region and the city of Konstanz. His work includes views of the lake, surrounding villages, harbors, and summer landscapes, subjects that appear consistently across auction records and regional listings. Kellermann’s paintings were sold and exhibited within German-speaking regions, indicating steady activity and recognition in local artistic circles.

Kellermann’s landscapes often depict Bodensee settings such as Konstanz, Reichenau, Arenenberg, and nearby rural valleys, suggesting that he lived and worked in the region for much of his career. Multiple documented works are signed and associated with Konstanz, reinforcing his connection to the area.

Kellermann remained active through the mid-twentieth century, producing paintings that continued to appear in auctions into the 1960s. He died in 1968, concluding a long career rooted in German landscape painting.
