After graduation from the Mechanical Engineering Department of Lviv Polytechnic in 1904, Bohdan Stefanowski pursued a career in industry as a specialist in heat management and then spent several years furthering his education under the supervision of Prof. Mollier in Dresden and Prof. Joss at Königliche Technische Hochschule in Charlottenburg.

In 1910, Bohdan Stefanowski returned to Lviv to continue his research at the Theory of Heat Engines Department headed by Prof. Tadeusz Fiedler.

In 1918 Bohdan Stefanowski returned to Warsaw where he assumed the post of Head of the Technical Thermodynamics Department and the Machine Laboratory.

[1] In the post-war era he managed to develop and equip the facility to European standards and both the Department and the Laboratory became a hub of vibrant scientific life.

In 1949 Prof. Stefanowski returned to Warsaw, where he rebuilt the Thermal Energy Laboratory and in 1951 he succeeded in commencing the building of the future Institute of Heat Technology to be opened in 1954.
