King Frederick the Great of Prussia (1712–1786) intended to erect a monument at Copernicus' grave in Frauenburg (Frombork), but the grave could not be located. Astronomer Nicolaus Copernicus (1473–1543) lived in Thorn (Toruń), then in the Kingdom of Poland, for many years.

Nicolas Léonard Sadi Carnot Nicolas Léonard Sadi Carnot Nicolas Léonard Sadi Carnot (; 1 June 1796 – 24 August 1832) was a French military engineer and physicist, often described as the "father of thermodynamics". Like Copernicus, he published only one book, the "Reflections on the Motive Power of Fire" (Paris, 1824), in which he expressed, at the age of 27 years, the first successful theory of the maximum efficiency of heat engines. In this work he laid the foundations of an entirely new discipline, thermodynamics. Carnot's work attracted little attention during his lifetime, but it was later used by Rudolf Clausius and Lord Kelvin
