Alexander McAulay (1863–1931) was an explorer of Clifford biquaternion theory and was the first professor of mathematics and physics at the University of Tasmania, Hobart, Tasmania. McAulay was born December 9, 1863 and attended Kingswood School in Bath. He proceeded to Caius College, Cambridge, there taking up a study of the quaternion algebra. In 1883 he published an article "Some general theorems in quaternion integration".〔A. McAulay (1883) Messenger of Mathematics 13:26 to 37〕 McAulay took his degree in 1886, and began to reflect on the instruction of students in quaternion theory. In an article "Establishment of the fundamental properties of quaternions"〔McAulay (1888) ''Messenger of Mathematics'' 18:131 to 136〕 he suggested improvements to the texts then in use. He also wrote a technical article〔A. McAulay (1888) "The transformation of multiple surface integrals into multiple line integrals", ''Messenger of Mathematics'' 18:139 to 45〕 on integration. Departing for Australia, he lectured at Ormond College, University of Melbourne from 1893 to 1895. As a distant correspondent, he participated in a vigorous debate about the place of quaternions in physics education.〔M.J. Crowe (1967) A History of Vector Analysis, U. Notre Dame Press. Chapter 6 details McAulay's four contributions in 1893 and 94 to the debate on vectors and quaternions.〕 In 1893 his book ''Utility of Quaternions in Physics'' was published. A. S. Hathaway contributed a positive review〔A. S. Hathaway (1894) (Review: ''Utility of Quaternions in Physics'' ), Bulletin of the American Mathematical Society 3(8):179–85〕 and Peter Guthrie Tait praised it in these terms: :Here, at last, we exclaim, is a man who has caught the full spirit of the quaternion system: the real ''aestus'', the ''awen'' of the Welsh Bards, the ''divinus afflatus'' that transports the poet beyond the limits of sublunary things! Intuitively recognizing its power, he snatches up the magnificent weapon which Hamilton tenders us all, and at once dashes off to the jungle on the quest of big game.〔PG Tait (1893) ''Nature'' 28 December〕 McAulay took up the position of Professor of Physics in Tasmania from 1896 until 1929, at which time his son Alexander Leicester McAulay took over the position for the next thirty years. Following William Kingdon Clifford who had extended quaternions to split-biquaternions, McAulay made a special study of this hypercomplex number system. In 1898 McAulay published, through Cambridge University Press, his ''Octonions: a Development of Clifford's Biquaternions''. McAulay died 6 July 1931. His brother Francis Macaulay, who stayed in England, also contributed to ring theory. The University of Tasmania has commemorated the McAulays' contributions in ''Winter Public Lectures''.〔University of Tasmania: (McAulay Lectures )〕 ==References== * Rev N. M.
