Angus Haldane has worked as a senior expert at both Christie's and Sotheby's, the world's leading auctioneers.

He has developed extensive experience of attributing, valuing, and researching pictures from the sixteenth century to the present day.

He studied Classics at Oxford University where he was drawn to the field of antique sculpture. He then studied for a post-graduate degree in Byzantine and Early Renaissance art at the Courtauld Institute, before joining the Bridgeman Art Library. It was from here that he moved to Christie's as a specialist in the Nineteenth, Impressionist and Modern Art Department.

After some years in this field he moved to Sotheby's to become a specialist in the field of British pictures where he worked from 2002 to 2007. He has lectured on the History of Art in Italy and Greece, and he is currently writing a book on the portraiture of the English Civil War.
