I am the daughter of Ossy Halpern, and niece of the late Berthold Halpern. I have only just now found more details about my late uncle and am so very sorry to hear about the passing of his wife Dorothea. I would be so glad to be in touch with any of the surviving family. My e-mail is dafna_da1@walla.com. with my sympathy Dafna Danay.. nee Halpern
