Ernő Gereben

Ernő Gereben (18 June 1907 – 16 May 1988) was a Hungarian–Swiss chess master whose half-century career extended from the mid-1920s to the late 1970s.

Born in Sopron, a Hungarian town at the Austrian border, Ernő Gereben used, until 1935, the German-language form of his name, Ernest (or Ernst) Grünfeld.

In 1934, he tied for 13–14th in Budapest (Maróczy Jubilee), which was won by Erich Eliskases.

Following World War II, Gereben played in several Hungarian Chess Championships.

Due to the Hungarian uprising in 1956, Gereben emigrated to Switzerland and began playing extensively in the west.

The British Chess Magazine editor, Bernard Cafferty, described him as "a delightfully friendly personality, rather different to many of the continental masters of that time.
