To bad he suffered in the end of his life.Lived in a box car with his family,committed to an insane asylum and a greater insult of having all his negs destroyed in the San Fransisco earthquake.
And his first set of negatives were "stolen" in a bankrupcy sale by his partner while he was out on a photo expedition. The set destroyed in the SF earthquake was his second set ("New Series", I believe).
Always has been one of my favorites -- I grew up with two of his prints in the hallway.
At least with LF landscape, a bad day of photography can still be a good day of exercise.
