He was also an accomplished lithographer[citation needed] and produced bird illustrations for the revised edition of Naumann's "Naturgeschichte der Vögel Mitteleuropas".

During his lifetime his works were acquired by museums in Rostock, Oldenburg, Kiel and Hamburg, and bought by numerous private collectors as far afield as Argentina and China.

[6] Prince Eitel Friedrich, the second son of Emperor Wilhelm II, acquired several of Müller-Kaempff's pieces for the imperial court in 1908.

[7] Müller-Kaempff stayed in touch with his former fellow-student, Georg Müller vom Siel, and visited him at Dötlingen in June 1908.

[9] Müller-Kaempff was so inspired by the isolated hamlet that he moved there, built himself a house in 1892, and started the painting school of St. Lucas in 1894.
