The article presents the person of Janusz Ballenstedt (1929–2005), a Cracow architect, whom twists of fate relocated to French circles. He was the designer of significant buildings in Poland, a man of great knowledge, skilful in his use of the pen. He transferred his thoughts regarding the all-encompassing viewing of architecture to paper. A valuable book, titled “Architecture – Theory and History” (PWN 2000) was written. The article is focused on J. Ballenstedt’s earlier unpublished work, a manifesto of the architect, titled Theory of Minimum in Architecture.
