Born in Ayrshire in 1936, Erni has been painting since childhood. He trained at Glasgow School of Art where his work reflected the influence of the Scottish Colourists who, like him, spent much time in the wonderful light and colours of the West Coast of Scotland. Painting in this tradition, he works with oils on canvas, using both brush and knife. In 1985, after working in banking for several years, he returned to Art and Design when he established an interior design company in Shropshire. He continued to paint in his spare time mainly for public and private commissions until 1999 when he sold the company and was able to devote more time to his art and to his love of sailing especially about the islands and coast of Scotland which he does every year. His work is exhibited throughout the UK and abroad.
