Henry George Forder (27 September 1889 – 21 September 1981) was a New Zealand mathematician.

Academic career

Born in

Auckland 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 received textbooks

.

His Foundations of Euclidean Geometry (1927) was reviewed by F.W. Owens, who noted that 40 pages are devoted to "concepts of classes,

parallel 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 the

Grassmann. He relied on methods of H. F. Baker

in Principles of Geometry to extend Genese's beginning into a complete development with applications throughout geometry. When The 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 the Ausdehnungslehre and the most inclusive treatment of the geometrical applications available at present."[2]

Henry Forder was elected

DSc from the University of Auckland in 1959.^[3]
