Duncan Liddel

Scottish mathematician and physician

The estate of Pitmedden was acquired by Duncan Liddel in 1600, serving as a material anchor for a career spent largely within European universities. Born in 1561 in Aberdeen, Liddel crossed borders to study and teach across Prussia, Silesia, and the German states, ultimately establishing himself as a significant figure in both medical science and mathematical instruction during the late sixteenth century.

Academic Foundation and Early Travels

Liddel received his initial education in languages and philosophy in Aberdeen before departing for the continent at age 18. His journey led him to the Viadrina European University in Frankfurt an der Oder, where he studied under John Craig. Following Craig’s return to Scotland, Liddel moved to Breslau, Silesia, to study mathematics under Paul Wittich. By 1587, he had relocated to the University of Rostock, where he focused on philosophy and earned his M.A. degree while forming connections with Johannes Caselius, Heinrich Brucaeus, and Cornelius Martini.

Career at Helmstedt

In 1590, Liddel joined the University of Helmstedt, where he advanced through the ranks of the faculty. He assumed the lower mathematical chair in 1591, succeeding Franciscus Parcovius, and later took the higher mathematical chair in 1594 following Erhardus Hoffmann. By 1596, he obtained his medical degree and began instructing students in physic. His service included acting as dean of the philosophy faculty in 1599 and pro-rector of the university in 1604.

Contributions to Science and Medicine

Liddel earned a reputation for teaching the astronomical systems of Copernicus and Tycho Brahe alongside the Ptolemaic system. His scholarly output included several medical texts, most notably Ars Medica, published in Hamburg in 1608. He also authored Disputationum Medicinalium Liber and De Febribus Libri tres, alongside a critique of contemporary superstition titled Tractatus de Dente Aureo, which debunked the claim of a boy possessing a golden tooth.

Endowments and Final Years

Returning to Scotland in 1607, Liddel utilized his accumulated wealth to support local education. In 1612, he provided lands to the University of Aberdeen for the maintenance of six scholars. The following year, he endowed a mathematics professorship at Marischal College. Liddel died on 17 December 1613, and was interred at St Nicholas, Aberdeen, with a memorial figure later placed at the site. His estate assets were largely distributed to the university and his brother, Peter Liddell.
