I am Peter Dicker (48), a writer from Holland. I am interested in any information about Ignaz Dicker, born in Kalusz (Poland) on June 10th 1889 and murdered in Sobibor on May 28th 1943. He lived for some time in Amsterdam, from where he was deported. His son Gustav died in Mauthausen in 1941. He was married to Eva Blauaug, born in Kalusz in 1894; time and place of death unknown. Looking forward for all your help writing a book!
