Fer Willemse deceased

Roy Kleukers - 3 January 2010

On 26th December, 2009 the Dutch orthopterist Fer Willemse has passed away, amidst his family in his hometown Eygelshoven. Fer was well known because of his large collection and his many publications, among which the catalogue and key to the Greek Orthoptera fauna and the recent world bibliography (together with Sigfrid Ingrisch).

Fer has helped many orthopterists throughout the world, with literature, specimens, identifications and advice. Many have visited his collection and library in Eygelshoven. Fer is the centre point of a family tradition in grasshopper study, featuring Cornelius (his father), Luc (his son) and Joost (his grandson). In June 2009 Luc  was proud to accept the David Rentz Award which was bestowed on Fer as a ‘life time achievement award’ by the Orthopterist’s Society.

Fer was diagnosed with lung cancer three years ago. He was happy to have been able to finish some big projects in his remaining time. He published an update on the Greek Orthoptera fauna and a major study on the Chorthippus of Greece.
