Duncan Liddel (also Duncan Liddell) (1561–1613) was a Scottish mathematician and physician. ==Life== Liddel was born in Aberdeen. Having received an education in languages and philosophy at the school and university there, he went abroad at age 18. After a few months he arrived at Frankfort-on-Oder, where a Scot, John Craig was teaching logic and mathematics; Craig superintended his studies. Three years later Craig returned to Scotland, and Liddel, on his advice, moved to Breslau in Silesia, where he studied mathematics under Paulus Wittichius, and encountered Andreas Dudith. In 1584 he returned to Frankfort, took pupils in mathematics and philosophy, and took up the study of physic. In 1587 an epidemic drove him to Rostock, where he became the friend of Johannes Caselius, Heinrich Brucaeus and Cornelius Martini; and received the degree of master in philosophy. With the help of his new contacts, he visited Tycho Brahe in 1587 and again the following year.〔 Shortly after his return to Frankfort in 1590 Liddel joined the new university of Helmstadt, established by Duke Julius of Brunswick. Caselius had already been appointed to the chair of philosophy there. Next year Liddel obtained the lower mathematical chair vacated by Parcovius, and in 1594 he succeeded Erhardus Hoffmann in the higher mathematical chair. In 1596 he became M.D. of the university, and began publicly to teach physic and to act as præses at the recitation of medical dissertations. In 1599 he was dean of the faculty of philosophy; in 1603 he resigned his mathematical professorship, and in 1604 became pro-rector of the university.〔 Liddel returned to Scotland in 1607, financially secure. In 1612 he endowed the university of Aberdeen with lands for the education and support of six poor scholars; and in 1613 he endowed a professorship of mathematics in Marischal College.〔 He died on 17 December 1613, at age 51. His funeral sermon was given by Gilbert Gray of Marischal College. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Duncan Liddel」の詳細全文を読む スポンサード リンク
