Saul Wexner (1890–1962) and Henryk Jakubowicz (1893–1943): Genealogy and Projects That Created Kraków’s Housing Environment, with a Focus on 1939–1945

This article explores the professional work of Saul Wexner and Henryk Jakubowicz, with particular emphasis on the buildings constructed in Kraków during 1939–1945. Its purpose is to enhance understanding of this valuable architectural heritage. The authors employed traditional research methods – such as literature review, analysis of design and official documentation, and on-site investigations – alongside genealogical research and microhistorical analysis.

The article concludes that Saul Wexner and Henryk Jakubowicz significantly shaped the urban fabric of Kraków, particularly its residential districts. Throughout their careers, they designed numerous buildings in Kraków – mainly residential tenement houses (around 30) – as well as public utility and industrial structures. These buildings have survived to the present day and are an important part of the city’s architectural heritage. They showcase the architects’ exceptional design skills and expertise, and also reflect their involvement in the technical and cultural development of their era. This is clear in their use of functionalist layouts, their pursuit of harmony between form and function, their focus on contact with nature, the application of reinforced concrete frames where suitable, and their refined choice of materials and aesthetic solutions.
