John Daniel Revel (1884–1967) was a Scottish painter and educator known for his portraiture and contributions to art education. Born in Glasgow, he studied at the Glasgow School of Art, where he developed a disciplined approach to drawing and painting, emphasizing careful observation and technique.
Revel’s work includes portraits, figure studies, and some landscapes, often characterized by a clear, precise style and a thoughtful, understated use of colour. Beyond his painting, he was influential as an art teacher and served as the Head of the Edinburgh College of Art from 1924 to 1932, shaping a generation of Scottish artists.
He is recognized today as an important figure in Scottish art, both for his skill as a painter and for his lasting impact on art education in Scotland.
