Marmaduke Tunstall (1743–1790) was a naturalist, antiquary and collector. Active in London during the 1760s and early 1770s, he built up an extensive Library and a Museum that was particularly notable for its systematic collection of British birds. Tunstall corresponded with several of the leading British naturalists, and with Linnaeus, and made his collections available for study to several authors. At the age of 33, Tunstall retired to a country estate at Wycliffe on the south bank of the Tees, where he spent the rest of his life. Newly-discovered information is incorporated with previously-published data, to provide a new account of Marmaduke Tunstall's life and activities, as a background to other studies on his family and his collections.
