194 FAMOUS GEOLOGISTS/Hall During his lifetime, du Toit was awarded many medals and honorary doctorates from five South African Universities His richly deserved Fellowship of the Royal Society of London was not awarded until 1943, possibly delayed by English prejudice against his continental drift ideas The greatest honour of all came when the Geological Society of South Africa instituted the biennial Alex L du Toit Memorial Lecture Series in 1949 A few years later, his image appeared on a South African stamp A collection of his notebooks is owned by the University of Cape Town The diaries for 1905, 1906, 1908, 1931, 1945, and 1946 are kept by the South African Museum in Cape Town A cache of photographs and documents, together with his academic gown, was recently donated to the Museum His awards, medals, and certificates are in the hands of a grandson See Also Famous Geologists: Suess; Wegener Gondwanaland and Gondwana History of Geology From 1835 To 1900 History of Geology From 1900 To 1962 Pangaea Plate Tectonics Further Reading Branagan DF (2004) The Knight in the Old Brown Hat: A Life of Sir T W Edgeworth David, Geologist Canberra: National Library of Australia Du Toit AL (1921) Land connections between the other continents and South Africa in the past South African Journal of Science 18: 120 140 Du Toit AL (1921) The Carboniferous glaciation of South Africa Transactions of the Geological Society of South Africa 24: 188 227 Du Toit AL (1926) Geology of South Africa Edinburgh: Oliver & Boyd Du Toit AL (1927) A Geological Comparison of South America with South Africa With a Palaeontological Contribution by F R Cowper Read Washington: The Carnegie Institution Du Toit AL (1937) Our Wandering Continents: A Hypoth esis of Continental Drifting Edinburgh: Oliver & Boyd Gevers TW (1949) The Life and Work of Alex L du Toit Alex L du Toit Memorial Lecture Johannesburg: Geological Society of South Africa Haughton SH (1949 [1950]) Memorial to AL du Toit (1878 1948) Proceedings of the Geological Society of America: 141 149 Haughton SH (1949) Alexander du Toit 1878 1948 Ob ituary Notices of Fellows of the Royal Society of London 6: 385 395 Holmes A (1929) Radioactivity and Earth movements Transactions of the Geological Society of Glasgow 18: 559 606 Rogers AW and du Toit AL (1909) An Introduction to the Geology of Cape Colony With a Chapter on the Fossil Reptiles of the Karroo Formation by Prof R Broom, 2nd edn London: Longmans Waterschoot van der Gracht WAJM (ed.)
