The Forder Lectureship is awarded by the London Mathematical Society to a research mathematician from the United Kingdom who has made an eminent contribution to the field of mathematics and who can also speak effectively at a more popular level. The lectureship is named for Professor H.G. Forder, formerly of the University of Auckland, and a benefactor of the London Mathematical Society. The lectureship was established in 1986 by the London Mathematical Society and the New Zealand Mathematical Society, and is normally awarded every two years. Recipients of the lectureship will give a four- to six-week lecturing tour of most New Zealand universities.
