John Rudolphus Booth

John Rudolphus Booth (April 5, 1827 – December 8, 1925) was a Canadian lumber tycoon and railroad baron. He controlled logging rights for large tracts of forest land in central Ontario, and built the Canada Atlantic Railway (from Georgian Bay via Ottawa to Vermont) to extract his logs and to export lumber and grain to the United States and Europe. In 1892, his lumber complex was the largest operation of its kind in the world.

He arrived in Bytown (later renamed Ottawa) at the same time as many other future lumber entrepreneurs such as Henry Bronson, W.G. Perley, John Harris and E.B. Eddy. Even so, by 1890 Booth had overtaken them all to become the largest lumber producer in the world. It was said that at one point the timberlands under his control occupied an area larger than France.

He was familiar with all aspects of his industry, and one observer noted:

[He] knew the forest as a sailor knows the sea, and his success was largely due to the fact that he never overestimated its potentialities.
