A few moments ago I received the sad news that Erhard Haus has passed away during this week end. All of us have had the opportunity of knowing him, reading with great interest his articles and books, discuss chronobiology with him during all the congresses of our specialty (he missed almost none of them). Those of us who had the additional blessing of having his friendship also whow how deep and warm was his humanity.

On behalf of you all, members of the ISC, I have already expressed to Erhard's family the feelings of loss and sorrow we are experiencing today.

I am asking our Secretary Prof. Hermida to post this sad communication on the ISC website, to make all colleagues aware of such unfortunate event and to spread our sincerest condolences to all colleagues.

For the same purpose, I am also inviting Professors Reinberg, Touitou and Smolensky to prepare an obituary that will be published in Chronobiology International as soon as possible.
