Ernő Csíki

Ernst Csiki, or Ernő Csiki (Csíki) (Hungarian: Csiki (Csíki) Ernő, 1875 in Vulkan – 1940s in Budapest) was a Hungarian entomologist who specialised in Coleoptera.

He was, between 1897 and 1932, Keeper of the Collections of the Hungarian Natural History Museum where his collection is conserved.

At the time of Ernő Csiki's retirement (1932) the beetle collection contained over 1 million specimens largely due to his purchases and his obtaining funding for expeditions. Csiki wrote several parts of Coleopterorum Catalogus and many papers on Carpathian Coleoptera.
