Dear Colleagues, this is very sad news indeed. I remember Claude very well, having met him and worked with him and Yves on several occasions, and also published a couple of papers together. Yves and I respected him tremendously for his valuable insights and  even named one of our genera in his honour. His papers on holothuroid taxonomy I find  very enlightening and use them all the time. Regrettably Parkinso'ns put a halt to his contributions and he will be sorely missed. My deepest condolences to his wife and family and hope they learn quickly to bear the loss. May his soul rest in peace.

Oh what a sad news :(. I remember his availability and welcome during my visit to the museum in 2012. He was sick but he did not hesitate to meet me and showed me his precious works on sea cucumbers and present me Yves who showed me the whole collection 

Rest In Peace Claude, We'll never forget you

Dear Colleagues/friends

Today, I have to bring you sad news.

Just yesterday, I've learned from Claude's wife that Claude has died; last Saturday...

It's extremely sad.

We've lost not only a colleague and a lot of expertise (and for some of us who knew Claude, a lot of friendship!)

Kind regards - yves

The Royal Belgian Institute of Natural Sciences (RBINS), is currently only partly open due to the coronavirus crisis. For the moment, data requests that require access to the collections can ad hoc be fulfilled, depending availability of staff. We do have remote access to our databases and can provide some assistance with data requests. We can also partly process loan requests and receive loan returns. However, visitors are not yet allowed to visit the collections. Thank you for bearing with us during this difficult time. Keep it Safe!
