Aatteiden mies: Piirteitä August Fredrik Soldanin elämästä

A chronological biography traces August Fredrik Soldan's life from cadet training through engineering studies, military service, and wide-ranging artistic and scientific interests, following his travels in Europe, engagement with revolutionary events, and subsequent exile. It describes years spent in Scandinavia, Britain, and North America where he teaches, invents, and conducts technical work, then returns home to participate in public projects, education, and industry. Alongside factual episodes the narrative offers reflective essays on religion, morality, national identity, and an unfinished philosophical manuscript, portraying sustained dedication to principles amid recurring personal struggle and intellectual restlessness.
