Fergus began his career at Sotheby’s in Sussex in 1979, joining the company as a trainee porter before a vacancy in the furniture department became available. With as many as two sales a month, this provided a broad grounding in English, European and early oak furniture.
In 1995 he was accepted for a specialist position in the English Furniture department, New Bond Street. This coincided with a booming market leading to the ground-breaking dealer stock auctions of John Keil and Michael Lipitch and the sale of a pair of Royal Queen Anne pier tables for over £1.5 million. After the millennium, Fergus was promoted to head of the English Furniture Department and landmark sales over the following years included those at Thornton Manor (The Leverhulme Collection), Easton Neston (Lord Hesketh) and other single owner collections such as property from Stanton Harcourt and The Safra Collection (New York). Fergus remained at Sotheby’s until 2010, his last year with the company featuring both The ‘Attic’ sale at Chatsworth House and a record auction price of £3.793m (aggregate) for The Harrington Commode by Thomas Chippendale. After Sotheby’s he transferred to Bonhams, London in 2011 as overall head of the Furniture department until 2015. Since then Fergus has been an independent consultant as well as working variously for Mallett, Dreweatts and the furniture vetting committee at Masterpiece.
