Thomas joined Christie’s in 2024 assuming overall responsibility for English Furniture & Clocks. Prior to joining Thomas spent 13 years at Sotheby’s during which time he was involved in many of the department’s most successful auction sales.

Alastair has acted as Head of the British & European Art sales in London since 2018, contributing to the success of the department’s many and varied sales. Alastair began his career at Christies in 2011 and led the 19th Century European & Orientalist Art auctions in Christie’s South Kensington to their highest results between 2014-2017. He played a significant role in Christie’s Amsterdam auctions in 2017.

Alastair is responsible for appraising and promoting European paintings and developing top client relationships throughout Europe, with a particular emphasis on Scandinavia and the Nordic regions. Alastair has a wealth of knowledge in this arena and has been involved with record breaking results for Scandinavian artists such as Vilhelm Hammershøi and Akseli Gallen-Kallela.

Alastair has established an extensive international network of collectors and museum curators. He has negotiated many private sales within this category. Alastair works closely with the Christie’s international team, having sourced business for auctions in London, Paris, Amsterdam and New York.

Prior to joining Christie’s, Alastair worked in a commercial art gallery exhibiting at Art Fairs throughout the UK. Alastair holds a M.Litt in Theology of Arts and the Imagination from the University of St. Andrews.

Sophie joined Christie’s in 2013 as specialist in medieval & Renaissance manuscripts, autograph letters, and archives. In 2025, after deciding that roughly 1,000 years of handwritten history wasn’t enough to contend with, her remit expanded to include printed books, becoming the only specialist internationally to work across all fields. Since 2019, she has been Head of Private Sales for the International Books and Manuscripts department, coordinating record-breaking years in London, Paris and New York and contributing to millions of pounds’ worth of private sales to individuals and institutions.

Sophie has had the pleasure of leading sales as diverse as the Metropolitan Opera Guild Collection of musical manuscripts and memorabilia (New York, 2017) and ‘Quentin Blake: A Retrospective’, an auction of works from Sir Quentin Blake’s personal collection sold to benefit charity (London, 2018), as well as working on the exceptional illuminated manuscripts from the collection of Elaine and Alexandre Rosenberg (New York, 2021). A recent favourite was ‘The Alphabet of Genius’ (London, 2023), a landmark sale of autographs which set new records in the field, from art (Saint-Exupéry) to science (Edmond Halley). In private sales, Sophie has sold works from a wide range of authors, reflecting her broad interests: from English literature (Keats) to science (Charles Darwin), with an emphasis on female authorship (Elizabeth Barrett Browning to Caroline Herschel).

Sophie has extensive experience in the valuation and sale of archives, both by private treaty sale and through the Acceptance in Lieu process: major sales have included the architectural archive of Sir Denys Lasdun (including original models for the National Theatre), the working archive of the much-loved children's author Shirley Hughes, and the family archives of the Barons Braybrooke, Earls of Dudley, and Marquesses of Londonderry.

Mark has over a decade’s experience in rare books and has been responsible for important sales in the fields of science, fiction, and science fiction, having set the record price for a work by a female scientist (Ada Lovelace’s Sketch of the Analytical Engine; £212,500), and overseen successful auctions including First Editions, Second Thoughts: An Auction in Support of English PEN (July 2022), Charlie Watts: Gentleman, Collector, Rolling Stone (September 2023), and Science Fiction and Fantasy (December 2024). In private sales, he has sold works by writers including Jane Austen, Victor Hugo, and Robert Burns, as well as several fine and inscribed copies of the first edition of Harry Potter and the Philosopher’s Stone. He was a co-curator of the Loan and Private Selling exhibition The Art of Literature in 2022, which brought together masterpieces like Shakespeare’s First Folio (1623), T. S. Eliot’s The Waste Land (1922), and pictures by artists including Rubens and Picasso. Mark holds degrees from the Universities of York and Oxford, where he specialised in the works of the Romantic poets, and has lectured on the life and poetry of his beloved John Keats.
