Greetings, I am Krystyna Kersten, a Polish historian known for my work on various topics including Communism, Jews in Poland, and post-war Poland. I was born on May 25, 1931, in Poznań and dedicated my life to the study of history and educating others at the University of Warsaw. My father's tragic fate in Katyn shaped my resistance to oppressive authorities and fueled my passion for uncovering the truth through my research and writing.
