Mary Ann Gwinn at the LA Times:
John Muir and Robert Underwood Johnson were unlikely allies in the war to preserve Yosemite. Muir, son of a Scripture-quoting Scottish immigrant father, was raised poor on a Wisconsin farm, but he wrote and spoke with the fervor of a prophet, and his craggy visage, tough constitution and unshakable devotion to the natural world drew admirers like a magnet. The urbane and cultured Johnson was an insider with a vast network of contacts in publishing and politics. The editor of one of the country’s preeminent magazines, Johnson hosted New York literary salons, mingled with America’s elite and eventually became the U.S. ambassador to Italy.
It was improbable that they even met — Muir was on the West Coast, Johnson on the East.
