Four European professionals are visiting Pittsburgh this week as part of the Marshall Memorial Fellowship of the German Marshall Fund of the U.S. The program sends the fellows to the U.S. for a month to visit several cities. While they're in Pittsburgh they'll spend time learning about economic development, education, arts and culture. They stopped by WDUQ to get a first-hand look at the business of public radio. In addition to WDUQ, Dobrina Cheshmedjieva of Bulgaria, Tamas Bodoky of Hungary, Pedro Rodrigues of Portugal, and Florian Toncar of Germany are scheduled to visit the Heinz History Center; meet with a PNC executive to learn about the financial crisis and banking regulations; ride on the Duquesne Incline; talk with the chief health officer of the Jewish Healthcare Foundation; and talk about American politics with a candidate who's running for Congress.
