  According to the Liber Memorialis of the University of Ghent, the Belgian
mathematician Paul Mansion (1844-1919) has published more than 349 academic
papers and books. For our part, we were able to calculate the correct number by
using the journal Das Jahrbuch \"uber die Fortschritte der Mathematik
(1869-1942). We concluded that Paul Mansion has published about 400 academic
papers and books.
