On the 10th of March 2015 in the Jewish Historical Institute dr. Andrzej Żor gave a lecture, concentrating on the complicated paths of capitalism development in Poland and the roles, that Jan Bloch and Leopold Kronenberg played in this process. Building capitalism in the XIX century Poland took longer and was more complex than in many other European countries. The reasons were both historical: partitions, diverting paths of capital movement due to the dismemberment of the land, uprisings and changes in the invaders' policies, as well as a specific economic structure, dominated by agriculture and typical attitudes, that remained in the collective consciousness. Knowing this, it is difficult to overestimate the role played by the pioneers of capitalism, among them the most influential and wealthiest businessmen of their time, both unfortunately almost forgotten by the XX century and modern historiography.
During a long and lively discussion many important topics were raised: the role of the Jewish bourgeoisie in the political life of the Kingdom of Poland and their involvement in the January Uprising (Kronenberg, Mikołaj Epstein), the role of women in business, ties, that connected Polish aristocracy to the Jewish financial circles, and the economic activity of other families: Fraenkels, Laskis and Epsteins, among others.
