Pirenne in Brussels before 1930. Guillaume Des Marez and the relationship between a master and his student.
Guillaume Des Marez was Pirenne's preferred student. In order to assure his student and friend Des Marez of a strong academic and professional position, Pirenne mobilised all of his networks. Both their relationship and Des Marez' career illustrate in an outspoken way which social transformations were, at the start of the 20th century, at work in the academic and scientific world.
