Sir George Steuart Mackenzie, 7th Baronet FRS FRSE FSA (22 June 1780–26 October 1848) was a Scottish geologist, chemist and agricultural improver.
Life
The only son of Major General Sir Alexander Mackenzie of Coul (d.1796), a General in the Bengal Army, by his wife Katharine Ramsay (d.1806), daughter of Robert Ramsay of Camno, he was born on 22 June 1780. He was tutored privately then spent one year at Edinburgh's High School (1795/6). He then studied sciences at the University of Edinburgh.
In 1796 he succeeded to the baronetcy aged 16, on the death of his father. He first became known to scientists in 1800, when he claimed a proof of the identity of diamond with carbon by a series of experiments concerning the formation of steel by the combination of diamonds with iron; for these experiments he is said to have made free use of his mother's jewels. In 1799 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were Sir James Hall, John Playfair and Thomas Charles Hope. He served as Vice-President of the Society 1844 to 1848. In 1815, 16 years after his fellowship of the Edinburgh Society, he was also elected a Fellow of the Royal Society of London. He was also President of the Caledonian Horticultural Society.
Pupil and friend of Robert Jameson, Mackenzie devoted much time to the study of mineralogy and geology. His interest in those subjects caused him in 1810 to journey to Iceland, when he was accompanied by Henry Holland and Richard Bright. To illustrate the conclusions he had formed with regard to the geology of Iceland, Mackenzie visited the Faroe Islands in 1812, and on his return read an account of his observations before the Edinburgh Royal Society.
He was also the landowner responsible for the clearances of the townships of Inverlael and Balblair near Ullapool during the winter of 1819-20, as part of the more general Highland Clearances. The clearances evicted hundreds of families from land by landowners to make way for large-scale sheep production or other agricultural uses. Some families relocated to other parts of Scotland, while others emigrated - many to Canada where their hardships continued. Evictions could be violent, and communities were forced to yield homes and land where generations of people had lived and worked.
Mackenzie died at his home, Kinellan House, in western Edinburgh, on 26 October 1848. His home is now subdivided as flats.
Works
In 1811, Bright, Holland and Mackenzie published Travels In Iceland; Mackenzie contributed the narrative of the voyage and the travels, and the chapters on the mineralogy, rural economy, and commerce of the island. It was reviewed favourably by Robert Southey (Quarterly Review, vii. 48–92). In this book Mackenzie first proposed explanation of periodic eruptions of geyser; he envisaged a geyser's underground system that includes a large cavern connected to the ground surface by a contorted conduit.
Mackenzie compiled a report for the Board of Agriculture: General View of the Agriculture of Ross and Cromarty, 1813. From 1826 to 1848 he contributed numerous papers to the discussion of the origin of the Parallel Roads of Lochaber, however his opinions did not gain acceptance. He also wrote:
- Treatise on the Diseases and Management of Sheep. With … an Appendix containing documents exhibiting the value of the merino breed, Inverness, 1807.
- Travels in the Island of Iceland during the Summer of the Year MDCCCX, Edinburgh, 1811.

Mackenzie married, first, 8 June 1802, Mary Macleod (d.1835), fifth daughter of Donald Macleod of Geanies, sheriff of Ross-shire, by whom he had seven sons and three daughters. The fourth son Robert Ramsay Mackenzie became Premier of Queensland. After her death (13 January 1835) he married in the next year, Catherine Jardine (d.1857), second daughter of Sir Henry Jardine of Harwood, and widow of Captain John Street of the Royal Artillery, by whom he had one son.
