Johan Fredrik Feyer (16 July 1821 – 26 June 1880) was a Norwegian industrial pioneer and factory owner.
He was the son of Christian Feyer (1793-1879) and Helene Othilie Falck (1792-1865).
His father was a state official and court administrator (sorenskriver).
During the 1840s, he traveled to Great Britain to study stoneware production.
[2][3] From 1865 the factory was known as Egersunds Fayancefabrik, producing the fine tin-glazed pottery on earthenware known as faience.
