Plesner (Norwegian family)

Plesner is a Norwegian family of Danish extraction, noted for its association with playwright Henrik Ibsen.

Many descendants of the family have occupied prominent positions in Norwegian society.

Johan Glüsing Plesner (1703–1735) from Kerteminde in Denmark migrated to Skien in Norway around 1720, where he became a merchant.

He was a son of merchant Bendix Jens Plesner (died 1708) and Anna Dorthe Bager (died 1748) of Kerteminde, and was married to Karen Cathrine Hind, a daughter of Kerteminde's mayor (rådmand) Knud Pedersen Hind.

Johan was the father of merchant Knud Plesner (1731–1790), married to Marie Roll (1741–1786).
