I am from the Czech Republic, a country in the heart of Europe that was profoundly marked by the events of World War II and the Holocaust. I was born thirty years after these events, yet as a child I was deeply influenced by my grandparents’ stories about how their friends, neighbors, and former classmates vanished from their community—deported to Nazi concentration camps and gas chambers. These memories left a lasting impression on me and sparked my lifelong interest in modern history. Since 2005, I have been writing books on historical subjects, and one of the first I explored was the Holocaust. In 2007, I published a book on this topic, which has now been released in a new, expanded edition. The book not only recounts the history of the Holocaust but also seeks to immerse readers in the atmosphere of the time through archival documents—carefully reproduced, either attached within the pages or placed in special inserts. With this work, I wish to honor the memory of all Holocaust victims and pay them the respect they deserve.
