Here is the mail Hans Janssen sent to Sciam on 17.02.2014:
The curator actually repeats what he had been telling in his letter of 01 April 2008: he works with so many people around the world who have very interesting ideas about Mondrian but Sciam's studies are for him not interesting enough.
Of course he forgets to mention that, thanks to the essay Sciam sent to him in 2006, he was finally able to understand things which, according to his own statement (see pages 154-155 of his 2005 Mondrian catalog for the Vienna Albertina Museum exhibition), "remained unexplained to him".
Is this maybe the reason why he cannot afford to acknowledge Sciam's contribution?
Mumble mumble.....
