Jakob, Bishop of Ösel-Wiek

Jakob (died 1337) was bishop of Ösel-Wiek from 1322, when Pope John XXII appointed him at Avignon. A former scholasticus of the Tartu cathedral chapter, he paid 1300 florins for his confirmation, almost as much as the other bishops combined, marking him as perhaps the richest man in Livonia.

In 1323 he fixed the bounds of Haapsalu's town territory with the vassals of Läänemaa, and in 1326 he fell into dispute with the archbishop of Riga. He died at Lübeck in 1337.
