Niall Logan held a personal chair in Systematic Bacteriology at Glasgow Caledonian University, and in 2017 was awarded the international Bergey Medal in recognition of outstanding and life-long contributions to the field of bacterial classification and identification. In 2020 a new genus of bacteria was named after him – Niallia! Although it did not become his career, his first love was archaeology, and he has now found his way back to it. A keen amateur of vernacular architecture, he has single-handedly restored his 18th-century farmhouse over 40 years, is Chairman of the Scottish Vernacular Buildings Working Group, a trustee of Auchindrain Township near Inveraray, and in 2013 he co-founded the Baldernock Local History Group. He devotes his time to landscape archaeology and archive study, from the post-medieval onwards, and to painting Scottish landscapes in oils.
