Interview conducted by Manuela Salvi, journalist at RTS.
Born in Geneva in 1944, Daniel de Roulet trained as an architect before becoming a telecommunications specialist. Since 1997, he has devoted himself entirely to writing and has received numerous awards. His cycle of ten novels, La simulation humaine, traces the journey of science, from its triumph to the questioning of its excesses. He is the author of around fifteen essays and travel narratives, including Légèrement seul: sur les traces de Gall (Phébus, 2013).
In Frontières liquides: journal de lacs (Phébus, 2025), the writer-walker, familiar with Lake Geneva, embarks on a single mission: to travel around border lakes, meet their inhabitants, and understand how to share and protect this common good. From the erased borders of Wannsee, where the fate of millions of Jews was decided, to Lake Victoria, where more than half of the fish stocks have disappeared in the last decade, passing through the Courland Lagoon, where Sartre and Beauvoir sealed the posthumous fate of Thomas Mann, the writer captures with sensitivity, poetry, and humor, submerged or tangible worlds.
