As an early member of the Münchner Kunstkreis (art circle), he promoted clarifies forms; emphasizing the connection between sculpture and architecture.
He was one of the founding members of the Munich Secession, and was a regular participant in their exhibitions, as well as serving on the jury panels.
In 1897, he was elected to the "Sachverständigen-Kommission zur Pflege und Führung der Kunst durch den Staat" (Expert Commission for the Care and Management of Art by the State).
The following year, Frederick I, Grand Duke of Baden, named him a Knight in the Order of the Zähringer Lion.
His son, the writer Michael Ende, has said that his time there served as inspiration for some of his fantasy stories.
