Dr. Zygmunt Klukowski was the chief physician of a small hospital in the village of Szczebrzeszyn, south of the city of Lublin, Poland. He kept a daily diary in which he chronicled the Nazi Occupation of his country in World War II. Because of the potential danger of discovery of his writings, he concealed his manuscripts, often changing their hiding place. This extraordinary document was published in Poland in 1959, shortly before his death, and subsequently translated into English. With this book, Dr. Klukowski became known worldwide as an important eyewitness to this period in Polish history.
