Wherever Muir traveled, he gathered plant specimens, often sending them to friends like post cards. The featured guest on this program is Bonnie Gisel, who searched out these artifacts for a new book. My only qualm about this otherwise fascinating program is Gisel's response to a caller who asked about Muir's role in driving indigenous people out of the Yosemite Valley. As with many biographers of great figures, she became more of an apologist than a scholar on this question, essentially explaining that Muir was less racist than his contemporaries.
See more about how Muir viewed indigenous Americans -- and how many of them view him today -- in my 2016 post Muir to the Story.
