"After Robert Dunsmuir (1825-89), British Columbia's first industrial magnate. Born in Kilmarnock, Scotland, Dunsmuir married Joanna (Joan) White in 1847. Promising that one day he would build her a castle on the Pacific, he persuaded her in 1850 to accompany him with their three children to Fort Rupert on Vancouver Island, where he worked for the HBC as a coal miner, soon being transferred to Nanaimo. After leaving the service of the HBC, Dunsmuir engaged in various rather unsuccessful ventures in coal mining until he discovered and obtain complete possession of the very rich deposits around Wellington. He also entered the lumber business, acquired an ironworks, built the Esquimalt and Nanaimo Railway, and became a very wealth man. During the last years of his life, he made good on the promise given years earlier to his wife, building Craigdarroch Castle in Victoria, though it was not completed under a year after his death."
