He went to University College of Wales, Aberystwyth, in 1896, and graduated with first-class honours in Physics in 1900. He then went to Trinity College, Cambridge, to study geology and mineralogy, 1902-1903. He joined H. M. Geological Survey to survey the western end of the south Wales coalfield. In 1909 he was awarded a DSc by the University of Wales, returned to Aberystwyth to lecture and in 1910 was appointed Professor of Geology. In 1919 he became Professor of Geology at the University of Manchester and in 1930 Woodwardian Professor of Geology at Cambridge University. He retired from his post in 1943.
