Simon Jones Murphy Sr. (April 2, 1815 in Windsor, Maine – February 5, 1905 ) was an American businessman.
Murphy was born in Windsor, Maine April 2, 1815, and was a lumberman there, beginning as a logger on the Penobscot River and working his way up. In 1866, he moved to Michigan and worked in lumber there as well. Operating out of Detroit, his company logged thousands of acres of Michigan pine forests. Murphy was one of the first millionaires in Detroit.
In 1887, Murphy began wintering in Whittier, California after purchasing the Ramirez Rancho. While there, he was an irrigator, citrus farmer, oilman, and real estate developer. He was founder of both the East Whittier Land and Water Company and the Murphy Oil Company, which drilled for oil in the Puente Hills. Murphy was an early benefactor of Whittier College. A hospital in Whittier bore his name, as does the neighborhood of Murphy Ranch, which was built on Murphy's citrus orchard.
In 1905, Simon Sr. completed the process of gaining control of the Pacific Lumber Company, which, under Murphy's control and stewardship, would become a storied and one of the largest Coast Redwood lumber and milling operations to ever exist. At least five generations of Murphy's, including Simon's son Simon Murphy Jr, Grandson Albert Stanwood Murphy, Great Grandson Stanwood Albert Murphy, and then Great great Grandson Warren Murphy managed and controlled with main offices and the bulk of its massive log decks and milling operations in the historic company town of Scotia in Humboldt County, California through 1985.
Murphy and his company built several buildings in the Detroit Financial District. These include the Marquette Building, the Murphy Power Building, and the first Penobscot Building A memorial commemorating Murphy exists in the second Penobscot Building.
