Emily Hahn's biography of Mabel (Ganson) Evans Dodge Sterne Luhan assembles the story of an 83-year-long life, some of it familiar to some of us but all of it probably to none. People who are closely interested in the incendiary Armory Show of modern art in 1913 may have read that Mabel Dodge was interested too; she lent her chauffeured car for the errands of the committee and contributed $500. People who are interested in John Reed, the revolutionary author of Ten Days That Shook the World, may remember that he was for a while her lover. More of us may recollect that Mabel went to Taos, New Mexico, and married an Indian, Tony Luhan, from the Taos Pueblo--partly because this is slightly more recent history, and partly because Mabel seems to have come more fully alive in that high dry Western air than she had in Buffalo, her birthplace, or presiding over salons in Florence and New York. It was there that she collected or rewrote her journals into six books of reminiscences that were widely reviewed and read during the Thirties, when the temporarily famous people of whom she wrote were still alive, in the flesh or in recent memory. . . Her name seems destined to be linked with that of D. H. Lawrence (Lorenzo); one is surprised to learn how brief their acquaintance was. Emily Hahn has worked hard with uncollected materials and interviewed as many people as she could reach. If her tone of voice sometimes seems tired or ironic (""After all, how would we know of Mabel's faults if she didn't tell us herself?""), this is a small fault in an engrossing book.
