Heinrich von Gagern
Robert Blum (10 November 1807 – 9 November 1848) was a German democratic politician, publicist, poet, publisher, revolutionary and member of the National Assembly of 1848. In his fight for a strong, unified Germany he opposed ethnocentrism and it was his strong belief that no one people should rule over another. As such he was an opponent of the Prussian occupation of Poland and was in contact with the revolutionaries there. Wikipedia
