Zentralblatt für Neurochirurgie, founded by Wilhelm Tönnis and Otfrid Foerster in 1936 in Leipzig, seems to address all the criteria for a journal. With its multinational editorial board (including Drs. Dandy, Cushing, and Putnam from the US) and regular, serial publications between 1936 and 1943, this journal addressed the many facets of a growing field, with articles spanning broad topics of interest. Because of the war, the publication of this journal was suspended.
The original Zentralblatt was reborn and exists to this day (as the Journal of Neurological Surgery Part A: Central European Neurosurgery)
