International Correspondence Chess Federation
On 15 August 1928, the ICSB (Internationaler Correspondensschachbund/International Correspondence Chess Federation) was created under the leadership of Erich Otto Freienhagen (Berlin), which had existed in a loose form since November 1927. Other members of the management were J.Keemink (Netherlands), K.Laue, H. von Massow, H.Schild (Germany) and C.Olsen (Norway). This was the first successful attempt to create an international correspondence chess federation. Unfortunately, it survived for only a short period, but its successor proved to be a viable and successful.
