The term rift valley entered the lexicon of global geography through the work of John Walter Gregory, who defined the feature as a linear depression formed by parallel faults. His career spanned continents, crossing from his initial training in London to major expeditions in East Africa, Australia, and eventually the Andes, where his life ended abruptly in 1932.
Formative years and education
Born in London in 1864, John Walter Gregory initially worked as a clerk in the wool trade before transitioning to the sciences. He pursued his education through evening classes at the Birkbeck Literary and Scientific Institution. His academic trajectory led to a BSc in 1891 and a D.Sc in 1893 from the University of London. By 1887, he had already secured a position as an assistant within the geological department at the Natural History Museum.

Gregory is associated with critical geological observations in East Africa, particularly during his 1893 visit to Kenya. His 1896 text, The Great Rift Valley, remains a foundational publication. Beyond Africa, he conducted significant fieldwork in Australia, documenting the geography of the Lake Eyre basin and the dynamics of dry lakes in Western Australia. In 1900, he joined the Discovery Expedition as director of the civilian scientific staff, though he resigned shortly before the voyage.
Academic leadership and output
In 1904, Gregory was appointed to the chair of geology at the University of Glasgow, where he mentored students including John Vernon Harrison. His administrative contributions were extensive, serving as president of the Geological Society of London between 1928 and 1930. He was a prolific author, producing works such as The Nature and Origin of Fiords, The Making of the Earth, and The Elements of Economic Geology, alongside forays into social topics such as human migration.
Final expedition and death
In 1932, Gregory embarked on a Royal Geographical Society expedition to the central Andes of Peru to conduct a geological traverse. While traveling on the Urubamba River, his canoe capsized. Gregory drowned, while his companion, Victor Coverley-Price, survived the accident. His death concluded a long career recognized by awards including the Bigsby Medal, the Victoria Medal, and the Keith Medal.
