International Correspondence Chess Federation (ICCF) was founded on 26 March 1951 as a new appearance of the International Correspondence Chess Association (ICCA), which was founded in 1945, as successor of the Internationaler Fernschachbund (IFSB), founded on 2 December 1928. The current president is Eric Ruch.
Some sources say that correspondence chess was already played in the 12th century.[1] Most chess historians doubt whether this is true. In the 19th century chess clubs and magazines started to organize more regular tournaments, national as well as international tournaments. Finally in 1928 the first international league (Internationaler Fernschachbund) was founded. Alexander Alekhine, Paul Keres and Max Euwe were well-known enthusiastic correspondence chess players during some periods of their chess careers.
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. It survived for only a short period, but its successor proved to be viable and successful.
On 2 December 1928, a new federation was formed in Berlin. To distinguish it from its predecessor, it was named the IFSB (Internationaler Fernschachbund). The founders were: R.Dührssen (President), J.Keemink (Vice-President), H. von Massow (Secretary), K.Laue (Teasurer) and L.Probst (Managing Editor).
Freienhagen (and others from ICSB) continue in parallel with the IFSB. Freienhagen died in 1933.
After this, correspondence chess players started joining IFSB. At that time, there was only individual membership and only later did it become possible for countries to be members.
IFSB Champions: Eduard Dyckhoff and Eugen Busch (Germany), 1929; E.Dyckhoff, 1930; A.H.Priwonitz (Germany), 1931; Hans Müller (Austria), 1932; Marcel Duchamp (France), 1933; Hilding Persson (Sweden), 1934; Paul Keres (Estonia), 1935; Milan Vidmar (Yugoslavia), 1936; Miklos Szigeti (Hungary), 1937 and Edmund Adam (Germany), 1938.
IFSB European Olympiad: the Hungarian Team (Balogh, Nagy, Szigeti, Barcza, Boros and Szucz) won the Final (1937-1939).
When the Second World War began, the IFSB Board decided to discontinue its activity.
