I have just received an email from Katharine Coleman who has passed on the sad news that he has passed away.
I cannot improve on what she says:
In case you have not heard, I write with great sadness to tell you of
the death this week of Jiri Harcuba. He had been in hospital for a couple of weeks in a deep coma.
I understand his funeral will be in Prague on 2nd August.
I am sure there will be fitting tributes to this great engraver, kind friend and inspiration to so many of us.
My sincere condolancies to Jiri Harcuba's family, and thank you Jiri for your wonderful work that has brightened many lives.
