Vitus Graber

He went to school in Innsbruck and a scholarship allowed him to study zoology at the Leopold-Franzens University in 1864 under Camill Heller.

He obtained a doctorate in 1868 and habilitated in zoology in 1871 with studies under Eduard Oscar Schmidt and wrote a thesis on the orthoptera of Tyrol.

[3] He dissected specimens of a range of insects and noted that they had sensory structures, then given the more generic name of chordotonal organs, which he believed were always involved in sensing sound and other vibrations, although it is now known that many were chemosensory in function.

[4] He demonstrated that Blatta germanica responded to sound, now known to be sensed through the anal cerci rather than chordotonal organs as he believed.

During the war in 1866 he served in the Innsbruck sniper company on the Lombardy border and received a medal for his service.
