In 2013, Bill Nesse digitized a trove of writings by Hans Martin Nesse, then researched at St. Olaf College and Luther Seminary to gather additional documents. His objective was to gather reliable written evidence for the timeline and events of Hans Nesse’s life (the father of Art Nesse, and grandfather of Bill Nesse). The documents gathered by Bill are indexed here: WDN Research Site. Bill completed a great book based on this information: Hans and Danielle Nesse.
