Courier Club was founded at the initiative of the staff of the Centre for Dialogue. Marek Edelman in Lodz. The idea has become a place bringing together young people interested in learning about the history directly at its source. Inspired idea was attributable to the 2014 100th anniversary of the birth of John Kozielewski, better known as Jan Karski. This remarkable figure whose legacy and mission were an attempt to rescue the morality of the world in the face of evil and tragedy of World War II is in our opinion an ideal hero for young, ambitious and looking for the Poles. Following the trails of Jan Karski reach the places connected with his mission, will conduct interviews with survivors. We will try to carry a message based on truth, tolerance, knowledge and adventure. We want to be modern emissaries developing and continuing on the legacy of this remarkable man.
