Olivier Rolin's The Weatherman recounts the true, poignant story of Aleksei Wangenheim, the first head of the Soviet weather service. Arrested during Stalin's Great Purge and sent to the Solovki Gulag, he maintained a connection to his young daughter through lovingly crafted letters, drawings, and herbariums. These artifacts attempted to teach her about the natural world while shielding her from the brutal reality of his imprisonment. Rolin masterfully reconstructs a narrative of profound paternal love and the resilience of the human spirit against the backdrop of totalitarian oppression.
