Bronislaw Kentzer , who gave his name to the building , managed the mill from 1938 to 1939 . Under his leadership , the production peaked up to 50 tons per day . In autumn 1939 , he was murdered by the Nazis , probably in Fordon 's Valley of Death . In 1940 the facility was taken over by German authorities . After World War II , the building was briefly in the hands of a Cooperative , " Społem " ( " Together " ) , then led by Jan Kentzer . After 1948 's nationalizations , the mill was managed by the State Cereal Plant in Bydgoszcz , using it to produce flour and other cereal products . Many significant structural changes occurred afterwards : in 1961 , steam engine was replaced for an electric one , and in the 1970s , offices , workshops , sheds and garages were built on the site of the demolished boiler room . At the end of the 1990s , the mill reached a record production of 100 tons of grain a day . At the same period , the company has been transformed into a Joint-stock company . This did not save the firm and in 2003 , the mill complex stopped its production , buildings being put for sale
