James Campbell (industrialist)

James Campbell, Esq. (February 4, 1826 – April 21, 1900) was a Scots-Irish industrialist in sugar cane processing, who became one of the largest landowners in the United States Territory of Hawaiʻi, and a real estate developer. He was an immigrant to Hawaiʻi from Ireland. At the age of 51, he married for a second time, to a young woman who was a daughter of Hawaiian aristocracy. They had eight children, four of whom survived to adulthood. One of their daughters married into the ruling family, and their grandchildren were heirs to the throne of the kingdom of Hawaii.

He established the Estate of James Campbell for his heirs, which continued for more than 100 years as one of the largest landowners in the islands. In 2007 more than 170 heirs agreed to rework it as the James Campbell Company; only three cashed out.
