Following his graduation from Chelsea School of Art in 1981, Alexander Pemberton won a British Council Award to work in Spain, and, in 1984, an Elizabeth Greenshields Award to work in Mexico.  He has since been based in London, teaching and painting, also working in France every summer.

He has exhibited at Cadogan Contemporary, Austin Desmond Fine Art and New Grafton Gallery among others.  In 1995-6 he won a commission for a large-scale mural at Sandwich Technology School, Kent (funded by the Foundation for Sport and the Arts). 

In 2002-3 he was commissioned by Biblelands charity to create an exhibition of paintings of Israel/Palestine, following a trip there. And then a further exhibition based on a trip to Armenia in 2004

The pursuit of objectivity has always been important in his work, from his training at Camberwell and Chelsea, which originated in the ideas of the Euston Road School.
