A personal friend of E.T.A. Hoffmann and a member of his literary club The Serapion Brethren(Serapionsbrüder), Koreff authored a treatise “Über die Erscheinungen des Lebens und über die Gesetze, nach denen es im menschlichen Organismus sich offenbart” and a volume of lyric poetry "Lyrische Gedichte" (published in Paris in 1815).
After about two years of gatherings at Hoffmann’s home or the Café Manderlee on the famous boulevard Unter den Linden, the circle gradually dissolved, partly, it is thought, because of the departure of one of its members, Adelbert von Chamisso, for a sailing trip around the world with the Russian Rurik Expedition, which had been organized to find a Northwest Passage (Kremer, 1999, 165).
