Julius Rosenwald and Rosenwald Schools Study Act of 2019 This bill directs the Department of the Interior to study the sites associated with the life and legacy of Julius Rosenwald, a part-owner and President of the Sears, Roebuck, & Company and a noted philanthropist. The study shall include a special focus on the Rosenwald Schools (the 5,357 schools and related buildings that were constructed in 15 southern states between 1912-1932). In conducting such study, Interior shall (1) determine which sites are of national significance, (2) prioritize the study of any Rosenwald Schools recommended to Interior by the State Historic Preservation Officer of any of the states in which such schools exist, and (3) determine the suitability and feasibility of designating one or more units of the National Park System to include those Rosenwald Schools and other sites representing Julius Rosenwald's life and legacy.
