Earlier this month, Stanford University announced it would rename Jordan Hall, named for David Starr Jordan, noted natural historian, ichthyologist, and Stanford's founding president back in 1891. Jordan's name is also coming off of several sites at Indiana University, where he also served as president. So who is this long-heralded, lately-demoted David Starr Jordan? He was, among many other things, a great obsession of Lulu Miller, co-host of Radiolab and author of the book, Why Fish Don't Exist: A Story of Loss, Love, and the Hidden Order of Life. In this podcast extra, Brooke and Lulu discuss Jordan's history, as well as the author's obsession with him, as a supreme taxonomist who sought determinedly to order the natural world — at least, in part, by finding and naming its fish and later, notoriously, by ranking its people.
