Robert Walker Macbeth was a Scottish painter, etcher and illustrator, active in the late 19th and early 20th centuries.
He was known for his pastoral landscapes, most of them rural or genre scenes with figures in various activities, and a suggestion of narrative content. His father and younger brother were also artists.
Macbeth was a member of the Royal Watercolour Society, the Royal Society of Painter-Etchers and Engravers, the Royal Institute of Oil Painters and the Royal Academy.
There are a number of scattered sources for his images online, unfortunately few are of high resolution.
