On March 2, 2009, five months before his pension, the renowned Orthoptera researcher Otto von Helversen passed away, as a result of a failed operation. Otto von Helversen for many years lead a successful university group on animal behaviour and evolution. One of his major contributions to Orthoptera studies was the development of a system to register the leg movements of Gomphocerinae together with the song. Unfortunately he has not lived to see the recent publication on Greek Chorthippus , of which he was co-author.
