Quick Reference

(1859–1939) When Alfred Harker entered St John's College, Cambridge as an undergraduate in 1878 he could not have foreseen that he would remain there for 61 years. During that interval he became one of the outstanding figures of British petrology. Harker began life at Cambridge reading physics, but soon transferred his affections to geology and was appointed a demonstrator at the Sedgwick Museum in 1884. He worked primarily on the volcanic and hypabyssal igneous rocks of the older Palaeozoic rocks in North Wales and the English Lake District. From 1895 to 1905 he worked with the Geological Survey in Scotland and commenced investigations of the Tertiary igneous province in the Hebrides.
