Longwell, Chester Ray (United States 1887-1975)
geology

Longwell's very full professional career featured leadership roles as a field geologist, college administrator, and writer (of both popular/educational and technical matter). First and foremost, perhaps, Longwell established his reputation in the field through structural and mapping surveys in both the western and eastern United States, e.g.: the Las Vegas/Lake Mead area, other parts of Nevada and Arizona, the Black Hills, and the Triassic zone of Connecticut and Massachusetts. A particular interest in geotectonics led him from time to time to consider worldwide patterns of development, and to chime in on ongoing debates such as that over Wegenerian continental drift.
