Eduard Killias

Eduard Killias (1 March 1829, in Chur – 14 November 1891, in Chur) was a Swiss physician and naturalist.

He studied medicine in Tübingen, Zurich, Bern, Prague and Vienna, obtaining his doctorate in medicine and surgery in 1852. Afterwards, he worked as a physician in his hometown of Chur and as a balneologist in Tarasp. He was long-time president of the Naturforschenden Gesellschaft Graubündens (1859–1891) and also served as vice-president of the Historisch-Antiquarischen Gesellschaft Graubündens.

He was the author of several works on bryophytes native to the canton of Graubünden, and in the field of entomology, he was principal author of the five-volume "Beiträge zu einem Verzeichnisse der Insectenfauna Graubündens". His studies on the mineral waters at Tarasp were later translated into English and published as "Tarasp and its mineral waters" (Nettleton Balme Whitby; publisher: London: Bosworth, 1870).

Taxa with the specific epithet of killiasii are named after him, an example being the moss species, Orthotrichum killiasii (Müll.Hal.).
