The History of Cologne's Jewish Citizens and their Persecution during the Nazi-era
Speaker: Dr Birte Klarzyk
Over the past four decades, the City of Cologne's NS-Documentation Centre (NS-DOK) has done extensive research on the history of Cologne's Jewish citizens and their persecution by the Nazi-regime. A core topic being biographical research and family histories, its staff has not only gathered information from various sources and archives, but also made contact with many survivors from Cologne and their families. In my presentation I will give an insight into the research activities and discuss how these can help descendants of Cologne's Jewish former residents trace their family history as well as show some examples from the NS-DOK's large collection of mainly personal records and artefacts pertaining to Jewish families such as letters, diaries and photo albums and speak about recent projects like a web-app jointly developed by the NS-DOK and the Jewish Museum MiQua offering different walks to sites relevant for Cologne's Jewish history in the 20th century.

Jewish Cattle Traders in the German Countryside, 1919–1939
Speaker: Dr Stefanie Fischer
In her book Jewish Cattle Traders in the German Countryside, 1919–1939: Economic Trust and Antisemitic Violence, Stefanie Fischer explores the social and economic networks in which this group operated and the informal but durable bonds between Jewish cattle traders and farmers that not even incessant Nazi attacks could break. Stefanie Fischer challenges the longstanding cliché of the shady Jewish cattle dealer by combining approaches from social history, economic history, and sociology. By focusing on trust and social connections, Fischer exposes the myriad inconsistencies that riddled the process of expelling the Jews from Nazi Germany.
