Life In 19x19

I am urgently seeking information about Felix Dueball. I come from the town where he was born. Today he is a completely unknown man there and I would like to prepare a lecture about him for the locals. I know that there is a biography of him by Mr Ciessow, but Mr Ciessow does not answer emails ...

Hi, my name is Rafał, I'm from Poland and I'm just starting my Go adventure. Warm greetings to all.
