About Alexander Logie du Toit
Alexander Logie du Toit FRS (14 March 1878 – 25 February 1948) was a South African geologist - an early supporter of Alfred Wegener's theory of continental drift.
the most important geologist in the history of South Africa. A field geologist with observational and synthetic powers of the highest rank, early in the twentieth century he embarked upon a twenty year study of the geology of South Africa which produced a series of important books and articles over the later portion of that period. Securing a grant from the Carnegie Institution of Washington in 1923, he spent five months in South America familiarizing himself with the geology of Argentina, Paraguay and Brazil, and comparing this to the units in South Africa; this led the publication of his A Geological Comparison of South America with South Africa in 1927, and the even more celebrated Our Wandering Continents; An Hypothesis of Continental Drifting in 1937. Du Toit had some success in convincing Old World geologists of the possibility of continental drifting but rather less with American observers; it was not until the plate tectonics revolution of the 1960s that the quality of his vision was first fully universally acknowledged.
