Margaret Peach grew up in Anglesey and studied Fine Art at Reading University, specialising in painting, particularly portrait painting.
She married and moved to Kelso in the Scottish Borders, and in the 1970s, as soon as her children were old enough, returned to commissioned painting and was soon working all over the British Isles and beyond, painting portraits of all kinds in a variety of settings.
In addition to portraits and other commissioned work, she has always enjoyed recording in paint the light and landscape of the Tweed Valley, and since a recent move to Watlington, the Thames, the Chilterns and Oxford. These paintings have formed the basis for sixteen solo exhibitions.
Commissioned work has been exhibited at the Royal Scottish Academy and the Royal Society of Portrait Painters. A recent portrait of Douglas Hall, who pioneered the setting up of the Scottish National Gallery of Modern Art, has been acquired by the Scottish National Portrait Gallery.
