Captain Robert Marshall (1863 – 23 July 1910) a retired army captain, was a Scottish playwright.
Robert Marshall's father was a magistrate in Edinburgh, who sent his son to school in St Andrews and afterwards to the University of Edinburgh, where he read Greek, Latin and English literature. His father's death curtailed his studies and he spent some time as the articled pupil of his uncle, a solicitor but he tired of this and chose to enlist in the 71st Highland Light Infantry, his brother having graduated from Sandhurst with distinction.
After three years service in the ranks, he was given a lieutenant's commission in the Duke of Wellington's West Riding Regiment, at that time stationed in the Bermudas. While on guard duty on Agar's Island, he used his off-duty time to write his first play The Subaltern, which was produced by The Amateur Dramatic Club of Bermuda for which he also acted and painted sets.
The regiment then moved to Canada where Marshall wrote a three-act play called Strategy which was produced in Halifax, being played by a first-class company from New York. His next piece was a burlesque entitled Guy Fawkes with music composed by the regiment's band-master.
The regiment then moved to Barbados where he again had great success with Guy Fawkes. While in Barbados, he wrote a play about the Jacobite rising of 1745–1746 entitled 1746 but although it was bought by an agent, it was never produced.
In 1893, he was posted to the Cape Colony as adjutant to Sir William Gordon Cameron, a post which he held for over a year. While stationed at the Cape Town Castle, he wrote a play entitled The Great Day which was to have been produced by George Alexander but F. Pigott, the Examiner of Plays (censor), objected to it and so this never occurred. A few months later his one-act play The Shades of Night was produced at the Lyceum Theatre.
