Adalbert Seligmann

He signed his criticism with the name "Plein-Air", in reference to a style of landscape painting known as En plein air.

His father was the Viennese medical historian, Romeo Seligmann so, from his youth, he was exposed to the intellectual circles of Austria.

He worked as a teacher of history painting at the Academy, as well as contributing art criticism and feuilletons to the Neue Freie Presse.

On an odd note, he possessed a skull fragment from Beethoven, that he had inherited from his father; preserving it in a secret location from 1936 to 1945.

His heirs donated the fragment to the Center for Beethoven Studies at San Jose State University, California, in 1990.
