John Muir

In 1866, John Muir's workplace was destroyed by fire. The factory, near Meaford, Canada, was not only where he worked as a woodworker and inventor of tools, but also where he stored his inventions, and a stock of wood he part-owned, all of which were lost in the fire. At the age of 27, he shortly changed his lifestyle to that of a naturalist and author.
