Biografisch Woordenboek van Nederland
The BWN is the successor to the Nieuw Nederlandsch Biografisch Woordenboek (NNBW) that was published between 1911 and 1937 in ten parts. This work only included people who died before 1910.
The biographies in the BWN were written by many different authors. Since 2002 all biographies are available for free online at the Institution for Dutch History, based in The Hague.
