Person: Milne (2), William
William P Milne studied at Aberdeen and Cambridge universities. He taught at Clifton College and then became Professor of Mathematics at Leeds.
Mathematical Profile (Excerpt):
 William Milne was educated at Peterhead Academy and Aberdeen Grammar School before going up to Aberdeen University.
 Almost ten years after he retired, Milne published Eppie Elrick, described at the time as a new doric classic.
 However, Milne was also interested in mathematical education and published a series of papers and mathematical notes in the Mathematical Gazette.
 Milne joined the Edinburgh Mathematical Society in December 1910.
 Even before he was formally through the procedure of membership, his papers were being read to the Society; Triangles Triply in Perspective by Charles McLeod and William P Milne, was communicated to the meeting on Friday 10 June 1910 by A D Russell.
 At the meeting at which his membership was confirmed, on Friday 9 December 1910, Milne read the paper A harmonic property of cubic curves.
 Further papers read by Milne to the Society include: The Focal Circles of Circular Cubics on 10 February 1911; The system of cubic curves circumscribing two triangles and a polar to them (communicated by Neil McArthur to the meeting of 10 November 1911); An easy geometrical representation of the Sextic Covariant of a Binary Quartic (communicated by Neil McArthur to the meeting of 10 November 1911); Investigations on Circular Cubics and Bicircular Quartics on 10 May 1912; Nonagons nonuply in perspective (communicated by N McArthur on 9 May 1913); Easy Proof of von Staudt's Theorem (communicated by P Comrie on 15 January 1915); The apolar locus of two tetrads of points (communicated by P Ramsay on 12 January 1917); and The coapolars of a cubic curve (communicated by Archibald Milne on 9 February 1917).
Born 22 May 1881, Longside, Aberdeenshire, Scotland. Died 3 September 1967, Glack, Aberdeenshire, Scotland.
