Jens Dinesen Jersin

Jens Dinesen Jersin (1588–1634) was a Danish Lutheran bishop. Educated at Herlufsholm and Wittenberg, he served as tutor to Christian IV's illegitimate sons and held teaching and parish posts in Copenhagen before becoming bishop of Ribe.

A Ramist, he issued Latin grammars that explained Latin partly in Danish, though his teaching method met fierce opposition from professors and schoolmen. As bishop he fought superstition, publishing in 1631 the first Danish work to argue that many reported wonders were imagination or fraud.
