This is the translation of Żydzi w Siedlcach 1850-1945 by Edward Kopówka from Polish into English. The town of Siedlce is in Warsaw province in central-eastern Poland, about 55 miles east of Warsaw. A Jewish presence in Siedlce is attested since the mid-16th century. Just prior to World War II, it had a Jewish population of around 15,000. About 10,000 Jews were deported to Treblinka in August 1942; the remainder of the Jewish community was liquidated in November 1942. This 452-page book chronicles the life of the Jewish community of Siedlce from the mid-19th century through its destruction during the Holocaust. Dr. Edward Kopówka (b. 1963) is a writer, historian, and educator. He holds a Ph.D. degree from the Faculty of History of the Podlasie Academy in Siedlce and is Senior Curator of the Museum of Struggle and Martyrdom in Treblinka. This book will appeal to scholars interested in the region or specializing in Jewish history and society as well as to Jewish genealogists seeking to trace their roots to Siedlce.
