The Polish author Stanislaw Przybyszewski and the German physicians Max Asch and Carl Ludwig Schleich were among the first in Strindberg's circle. Later, the critics Franz Servaes and Julius Meier-Graefe joined the group, together with Richard Dehmel and many others. The originally German circle was also joined by several Scandinavians. Sigbjørn Obstfelder, Gustav Vigeland, Frits Thaulow, Hulda and Arne Garborg, Oda and Christian Krogh were all guests of the famous tavern. Finnish-Swedish Karl A. Tavaststjerna belonged to the Ferkel-circle, as did the Polish Alfred Wysocki.
