Stewart McGlashan or McGlashen (1807–1873) was a Scottish sculptor and mason, responsible for creating the company Stewart McGlashen (sic) which flourished from 1842 to 1974. He was responsible for devising a series of machines capable of creating highly polished granite (sometimes with a mirror finish) for the first time, and capable of carving intricate designs accurately and fast. At his time he was not held in high esteem by sculptors who saw him as undermining their artistry. Despite not being "hand-carved" the artistry value of his work is exceptionally high.

He was very fond of the use of pink and red granites rather than the typical grey granites. His work is usually done as a single piece of granite, except in unusual pieces such as the Dean Cemetery pyramid.

His work was in high demand and changed the face of cemetery design, also adding immeasurably the durability of monuments.

He was born in Campbeltown in western Scotland on 2 November 1807, the son of James McGlashen or McGlashan, a builder. He was christened on 17 November.

In 1842 he set up a monumental mason business at the entrance to the newly opened Southern Necropolis in Glasgow, living at that time at 81 Lawmoor Place, nearby to the south (now demolished).^[1]

In 1846 he moved to Edinburgh and set up a yard immediately north of the entrance to Dean Cemetery (later absorbed into the first cemetery extension in 1871). He was living at Canonmills Bridge where he had a second yard and an office.^[2] This was more publicly visible, and in theory served Warriston Cemetery in the north of the city.^[3]

By 1865 he was living in a house at 6 Huntly Street, close to the Canonmills yard. He brought his son, Stewart McGlashan (1844–1904) into the firm around this time, creating McGlashan & Son. From 1881 (without explanation) the spelling of the company changed to McGlashen. From around 1875 they had a sister company (involved in quarrying) the Edinburgh Granite and Stone Company.^[4]

He died of heart disease at home 1 Eyre Place in Canonmills, Edinburgh on 9 September 1873. He is buried in Warriston Cemetery. The modest granite stone lies in the overgrown area to the south-west and is hard to access.

In 1898 the company opened a third yard at 8 Grange Road serving Grange Cemetery.^[5]

Stewart McGlashan Jr was also buried in Warriston Cemetery. His grave is marked by a "typical" McGlashan Celtic cross.

The company became a subsidiary of Balfour Beatty in 1974.^[6]

The Canonmills office and yard on Canonmills Bridge survived until 2019 when they were demolished for a housing development.^[7]

In 1833 he married Mary Buchanan (1810–1907) at the Barony Church in Glasgow. They had at least nine children, two of whom died in infancy.
