Biography
Morton was a British abstract artist, born in Carlisle, Cumberland, to which he eventually returned after some years in Edinburgh. His family owned a textile firm, Morton Sundour, being based in Edinburgh and Cumberland. Morton joined the firm at the age of 21, having studied mathematics for a year at Edinburgh University and briefly attended Oxford University. In 1928, his father, James Morton, founded Edinburgh Weavers, to which Alastair was eventually appointed Artistic Director. This brought him into contact with many contemporary artists who used the firm, notably Ben Nicholson and Barbara Hepworth. From the mid-1930s, Morton began to work in a manner similar to the Nicholsons, exhibiting in group shows. An exhibition of Morton's work focused on his involvement with Edinburgh Weavers was held in 1978 at Scottish National Gallery of Modern Art, which holds his work.

The Fine Art Society held a major show of his work in 2006.
