Frans Ackerman

He was assigned leader of the rebellious" Reisers" by Philip van Artevelde, and accountable for the victories against Count Louis II of Flanders.
While he travelled to England in 1382, in an attempt to find support for Flanders against the attacking French, Van Artevelde died in the Battle of Roosebeke and all Flanders but Ghent was subdued by Count Louis.

Ackerman was murdered two years later by a son of the Lord of Herzele who deemed him responsible for the death of his father.
