 A major contributing factor to Scheler’s productivity at this time was his introduction to the Göttingen circle of phenomenology. Along with the great master, Husserl, this circle included such young and promising thinkers as Adolf Reinach, Hedwig Martius, Roman Ingarden, Alexandre Koyré and Edith Stein. He met and later joined the circle after the invitation in 1912 to give private lectures in Göttingen. Because Scheler was forbidden to teach at a German university his lectures would often have to be held in hotel rooms rented by his close friend Dietrich von Hildebrand. It was also at this time that Scheler became co-editor, along with Husserl, Alexander Pfänder, Moritz Geiger and Adolf Reinach, of the greatly influential journal, Jahrbuch für Philosophie und phänomenologische Forschung.
