"As great-grandson I grew up with all of these family stories, however I never had the opportunity to get to know Sergej Stepanowitsch. My interest in these stories goes far beyond the family ties: the history of the twentieth century in its entirety, its events, its contradictions and its possibilities are all mirrored in this complex family saga."

Sergej Stepanowitsch Tschachotin’s courage and zest for action obviously went far beyond the ideas and conventions of his day, and this can be fascinating and frightening at the same time. The topicality of the questions and themes in Tschachotin’s biography intrigue me: cancer research, cell manipulation as a forerunner of genetic research; the notion of a worldwide scientific network (and the way knowledge moved about the world in the era before the internet); propaganda processes and their effectiveness in combination with the media; political and social activism; the theme of atomic weapons (the unstoppable arms race and the threat the weapons pose to any stable world peace). While working on this film, I came to understand that the networks and boundaries in each of our families are perhaps the most archaic and – at the same time – the most stable. These are the true networks and boundaries, the ones we must navigate our entire lives, ones which we may relish but cannot escape.
