SIr James Hall's house128 George Street, Edinburgh EH2 4JZ

Sir James Hall was a important champion of the theories of James Hutton. He was with Hutton when he discovered his famous unconformity at Siccar Point in the Scottish Borders. Hall played a major role in the debate between the disciples of Hutton (Plutonists) and those of the German geologist Abraham Gottlob Werner (Neptunians). Starting in 1798, he conducted a series of experiments to prove the Huttonian principle that the earth’s internal heat played an vital role in rock formation. These involved making artificial marble by subjecting powdered chalk to intense heat and pressure.

The ground floor Sir James Hall’s house is now a Wetherspoon pub.

Archibald Geikie's houseRamsay Gardens, Castle Hill, Edinburgh EH1 2NA

Collaborating with Roderick Murchison, Archibald Geikie produced the first geological map of Scotland in 1862 while working for the Geological Survey of Great Britain. He went on to become the first professor of geology and mineralogy at the University of Edinburgh from 1871 to 1881 and then head of the Geological Survey in 1881. He published widely on subjects as diverse as glacial drift (1863), the scenery of Scotland (1865) and the extinct volcanoes of Britain (1897). In 1976 he had a ridge on the Moon, Dorsa Geikie, named after him.

Memorial to John Playfair on Calton Hill

38 Calton Hill, Edinburgh, EH7 5AA

Mathematician, physicist and geologist, John Playfair is perhaps best known as James Hutton’s most influential disciple. His Illustrations of the Huttonian Theory of the Earth (1802) probably did more to popularise his theory than Hutton’s own notoriously impenetrable writings.  In his career he was consecutively professor of mathematics and professor of natural philosophy at the University of Edinburgh. As first president of Edinburgh Astronomical Institution he enthusiastically supported the construction of Edinburgh’s observatory on Calton Hill, which his monument stands beside, but sadly died before its completion.

John Walker's grave.Canongate Kirkyard, 153 Canongate, Edinburgh EH8 8BN

John Walker was the University of Edinburgh’s second professor of natural history from 1779 to 1803, but the first to take his teaching responsibilities seriously. Walker was primarily a mineralogist and had little time for speculative theories of the earth. He was also an enemy of evolutionary speculation and described the transmutation of species in his lectures as ‘a vulgar error’. He took his students on regular field trips and held tutorials in the University’s natural history museum, of which he was also the keeper.  In both of these practices he was followed by his successor, Robert Jameson.

Hutton's sectionRadical Road, Edinburgh EH8 8AL

At this site James Hutton found proof for his theory that heat plays an essential role in rock formation.  He believed that a band of molten rock had been injected into older strata long after the formation of the surrounding rock. During Charles Darwin’s time as a medical student in Edinburgh in 1825-7 he accompanied the professor of natural history, Robert Jameson, on a field trips to Salisbury Crags. Darwin later recalled being deeply unimpressed by Jameson’s explanation that these intrusive rocks had been deposited from above by precipitation from the sea rather than injected as magma from below.

A plaque at the site give some interesting information on its history and significance.

Offices of the Witness newspaper.297 High Street, Edinburgh EH1 1YJ

Hugh Miller was one of the most remarkable figures in 19th-century Scotland. At this address between 1840 and 1856,  Miller edited the Witness, the newspaper of the Free Church of Scotland. It was in the Witness that he first serialised many of his geological works, including The Old Red Sandstone (1841). Having started his working life as a stonemason, this self-educated geologist went on the make important contributions to palaeontology. In particular, he was a pioneer of paleoecology. A fierce opponent of evolution on religious grounds, and plagued by mental-health problems, he tragically took his own life in 1856.

Giant Irish Elk skeleton.National Museum of Scotland, Chambers St, Edinburgh EH1 1JF

The magnificent skeleton of this extinct beast was added to the collection of Edinburgh University’s natural history museum in 1821 by Robert Jameson. It is not in fact a close relative of modern elks, but is a species of extinct giant deer. The skeleton was discovered in a bog in Ballaugh on the Isle of Man, and brought to Edinburgh through the efforts of the Duke of Atholl. This remarkable creature was at the centre of early debates on extinction. The great French geologist, Georges Cuvier, famously used it as an example of a species that was now completely extinct.

Comemorative pillar, the Meadows.The Meadows, Melville Drive, Edinburgh EH3 9EX

These two commemorative pillars were erected in 1886 by the Master Builder and Operative Masons of Edinburgh for the International Exhibition of that year. The blocks of stone from which the pillars are constructed represent stones from the different quarries which supplied Edinburgh in the 19th century. The names of the quarry from which it was extracted is carved on each stone. After well over 100 years, the different weathering qualities of the stones are evident.

James Geikie house16 Duncan Street, Edinburgh EH9 1SR

James Geikie was professor of geology and mineralogy at the University of Edinburgh from 1882 to 1914, succeeding his brother Archibald Geikie in the chair. He had previously worked for the Geological Survey since 1861. His fame rests largely on his work on the ice ages of the Pleistocene epoch. He developed the hypothesis that there had been five interglacial periods between the ice ages. In his The Great Ice Age and its Relation to the Antiquity of Man (1874) he proposed that humanity had continued to inhabit Europe throughout the ice ages.

National Museum of Scotland

The oldest part of the building that houses the National Museum of Scotland was called the Edinburgh Museum of Science and Art when it was opened by Prince Albert in 1866. Construction had began in 1861 and work was to continue on the first phase of the building until 1888. It was renamed the Royal Scottish Museum in 1904 and became the National Museum of Scotland in 2004. Initially much of the collection came from the University of Edinburgh’s natural history collection, which had become too big for the University’s own museum in what is now the Talbot Rice Gallery.

Free entry, although some temporary exhibitions may charge.
