- Harry Lindgren
Harry Lindgren (1912–1992) was a British/Australian engineer, linguist and amateur mathematician. He was born in Newcastle-on-Tyne in England.
In 1935 he emigrated to Australia. He received a B.Sc. degree from the
University of Western Australia and later became a Commonwealth Patent Officer.Contributions to mathematics
Lindgren published articles in several mathematical journals which culminated in his famous book 'Geometric Dissections' (Van Nostrand 1964), which explores techniques for devising and solving
dissection puzzle s. When published, his work was the only complete treatment of this subject in any language. [According toMartin Gardner writing in "The Unexpected Hanging" (Simon & Schuster, 1969)] This remained true for a third of a century. [See "Dissections: Plane & Fancy", Greg N. Frederickson (Cambridge University Press, 1997)]Contributions to linguistics
In 1969 he published "Spelling Reform: A New Approach" (Alpha Books, 104 Bathurst St, Sydney 2000, Australia). This work outlines a proposal for introducing phoneme-by-phoneme adjustment of English spelling, in order that spellings may more accurately represent the sounds of the speech they denote. The book features several cartoons illustrating the absurdities of existing spellings.
On September 1, 1971 he launched the
Spelling Action Society to promote his suggested reforms. He chose the name (which shares its initials with Scandinavia's SAS airline) so as to acknowledge his Nordic ancestry. He published the newsletter Spelling Action under the society to promote use of his Spelling Reform step One (SR1). As Lindgren's health deteriorated in later life the newsletter was taken over by Gary Jimmieson (and later Doug Everingham).References
