Novelist and Journalist. Born at Inveraray (Argyll and Bute), Munro was the illegitimate son of a kitchen-maid, with the rumour that his father was a member of the Duke of Argyll's family. He was educated at Inveraray School. He moved to Glasgow where he became a journalist, rising to become the Assistant Editor of the Glasgow Evening News (1918-27). A noted author of historical novels, Munro is best known for the humorous adventures of the crew of a Clyde puffer, the "Para Handy" stories, which he wrote under the pen-name Hugh Foulis.
Munro received honorary degrees from the Universities of Edinburgh and Glasgow. He died in Helensburgh and lies buried in Inveraray. A monument to his memory was unveiled in Glen Aray in June 1935.
