Ralph Adron studied theatre design at Croydon College of Art with the painter and theatre designer Frederick Crooke and then at the Slade School of Fine Art. Most of his theatre work is now held at Bristol University Theatre Collection. He taught design and drawing at various art schools and colleges during his working life. As well as theatre work he designed for interiors carrying out decorative finishes, textiles and furniture. He has always painted and has work in many private and public collections.

Today he paints practically full time. His aim is to paint a non-existent world which has no, or little, narrative or anecdotal content. The paintings are deliberately two dimensional in the manner of traditional stage scenery and rely on the colour and texture of their supports for interest. The line is simple and repetitive; the figurative subjects cartoon-like.
