Henry George Forder (27 September 1889 – 21 September 1981) was a New Zealand mathematician.
Born inShotesham All Saints, nearNorwich, he won a scholarships first to a Grammar school and then toUniversity of Cambridge. After teaching mathematics at a number of schools, he was appointed to the chair of mathematics atAuckland University College in New Zealand in 1933. He was very critical of the state of the New Zealand curriculum and set about writing a series of well receivedtextbooks.
HisFoundations of Euclidean Geometry (1927) was reviewed by F.W. Owens, who noted that 40 pages are devoted to "concepts of classes,relations, linear order, non archimedean systems, ..." and thatorder axioms together with a continuity axiom and a Euclideanparallel axiom are the required foundation.The object achieved is a "continuous and rigorous development of the [Euclidean] doctrine in the light of modern investigations."[1]
In 1929 Forder obtained drawings and notes of Robert William Genese on theexterior algebra ofGrassmann. He relied on methods ofH. F. Baker inPrinciples of Geometry to extend Genese's beginning into a complete development with applications throughout geometry. WhenThe Calculus of Extension appeared in 1941 it was reviewed by Homer V. Craig: "The theorem density is exceptionally high and consequently despite the superior exposition it is not an easy book to work straight through – perhaps the key chapters suffer from a lack of recapitulation...[It] provides the best exposition of the fundamental processes of theAusdehnungslehre and the most inclusive treatment of the geometrical applications available at present."[2]
Henry Forder was electedFellow of the Royal Society of New Zealand in 1947 and received an honoraryDSc from theUniversity of Auckland in 1959.[3]
TheForder Lectureship was established jointly by theLondon Mathematical Society and theNew Zealand Mathematical Society in his honour in 1986.[4]
