He was a pioneer of bird acoustics and worked along with Hans Stadler to produce phonograph recordings and apply ideas from music to their description.
In 1909 he moved back to the Lohr Preparatory school as a director and began to deal with natural history and music teaching.
Here he met Hans Stadler (1875–1962), the engineer Pleikart Stumpf (1888–1946) and Adam Guckenberger (1886–1964).
He was influenced by the philosophy of Berthold Otto and his approach to education was the concept of wholeness or holistic perception.
He published several books including "Wege zur Naturliebe" (Pathways to Nature Appreciation); "Lebenskampf und Anpassung der Pflanze – 300 Versuche und Beobachtungen" (Struggle for Life and Adaptation of Plants - 300 Experiments and Observations); and "Lebensgemeinschaften der deutschen Heimat" (Life Communities of the German Homeland).
