Alexander Logie du Toit FRS ( ; 14 March 1878 – 25 February 1948) was a geologist from South Africa, and an early supporter of Alfred Wegener's theory of continental drift.
Alfred Lothar Wegener (none }}  – none }} ) was a German polar researcher, geophysicist and meteorologist.
Continental drift is the movement of the Earth's continents relative to each other, thus appearing to "drift" across the ocean bed.
 The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.
 The concept was independently and more fully developed by Alfred Wegener in 1912, but his theory was rejected by some for lack of a mechanism (though this was supplied later by Arthur Holmes).
 The idea of continental drift has been subsumed by the theory of plate tectonics, which explains how the continents move.
Stefanus Du Toit is a South African inventor and entrepreneur and a co-founder of Waterloo-based RapidMind, a company specializing in the development of software that automatically parallelizes serial code.
 The technology behind Rapidmind was developed by Du Toit during his graduate research at the University of Waterloo.
 As of 2008, RapidMind has raised $10M in venture capital financing.
 RapidMind was acquired by Intel in 2009.
 In 2008 Du Toit was honored by being included in the MIT Technology Review's TR35 list.
Pieter Stephanus du Toit (born 20 August 1992) is a South African rugby union footballer.
 Du Toit plays as a lock or a flanker, and represents Western Province in the Currie Cup and the Stormers in Super Rugby.
Jacobus Francois "Flooi" du Toit (2 April 1869 – 10 July 1909) was a South African cricket player.
 With just one match to his name, du Toit has the distinction of making a combined first-class and Test debut.
 Along with G. Cripps, C.G. Fichardt and E.A. Halliwell, also combined debutants, du Toit was selected for the only Test match against a touring England side led by W.W. Read in 1891/92.
 In a match won handsomely by the visitors (by an innings and 189 runs), du Toit scored 0 not out and 2 not out, took one wicket for 47 runs, the England captain’s no less, and held one catch.
Du Toitskloof Pass (English: Du Toit's Rift) is situated in the Western Cape province of South Africa, on the Regional road R101 between Paarl and Worcester.
 The pass was named after Francois Du Toit, a 17th-century Huguenot pioneer who settled in the foothills.
 It was initially an animal track where a road was built around the time of World War II.
The Du Toit Mountains ( ) are a group of mountains about 35 mi long and 10 mi wide, to the south-west of the Wilson Mountains in southeastern Palmer Land, Antarctica.
 The mountains have peaks rising to 1,700 m and are bounded by Beaumont Glacier, Maury Glacier and Defant Glacier.
 They were first photographed from the air by the U.S. Antarctic Service in 1940; rephotographed by the U.S. Navy, 1966–69, and mapped from the photographs by the U.S. Geological Survey.
 In association with the names of continental drift scientists grouped in this area, they were named by the Advisory Committee on Antarctic Names after Alexander du Toit, a South African geologist who was an early proponent of the theory of continental drift.
The Du Toit Nunataks ( ) are a group of nunataks between Cornwall Glacier and Glen Glacier, marking the western end of the Read Mountains, Shackleton Range.
 They were photographed from the air by the U.S. Navy, 1967, and surveyed by the British Antarctic Survey, 1968–71.
 In association with the names of geologists grouped in this area, they were named by the UK Antarctic Place-Names Committee after Alexander Logie du Toit, a South African geologist.
Sir Edward "Teddy" Crisp Bullard FRS (21 September 1907 – 3 April 1980) was a geophysicist who is considered, along with Maurice Ewing, to have founded the discipline of marine geophysics.
 He developed the theory of the geodynamo, pioneered the use of seismology to study the sea floor, measured geothermal heat flow through the ocean crust, and was one of the first to find new evidence for the theory of continental drift.
