The article is devoted to Architect Jerzy Jakubowicz, the designer of one of Warsaw’s most iconic buildings—the PKO Bank Rotunda. Jakubowicz started his studies at the Faculty of Architecture of the Warsaw University of Technology prior to World War II. During the war he served as an RAF pilot. In 1946 he completed his studies at the Polish School of Architecture in Great Britain. At the turn of the 1950s and 60s, after about twenty years of emigration, he returned to Poland and worked with the team of Zbigniew Karpiński on the designs for the Eastern Side of Marszałkowska Street in Warsaw. His participation primarily involved the development of designs for the Wars and Sawa department stores (together with Architect P. Zajlich) as well as the PKO Bank pavilion, referred to as the PKO Bank Rotunda. Jakubowicz again emigrated in the second half of the 1960s. This time it was to the United States where is spent the rest of his life.
