Prior to founding SEYDOUX & ASSOCIÉS Fine Art, Seydoux co-founded and headed (from 1995) the Art Advisory Department of Schroders Banque in Geneva, Switzerland from 1990 until 1997. In the spring of 1997, he joined Christie's as an International Specialist in the Impressionist and Modern Art Department in London, before moving to Paris and Geneva in 2000. He was the international Co-Head of the Department with Guy Bennett from 1997 until 2012, when he was named International Chairman of the Department.

Credited with securing a number of record-setting pictures — including Picasso's Nude, Green Leaves and Bust, which sold for $106.5 million in 2010 — Seydoux also proved his mettle as a team leader. That leadership was on display in the organization of Christie's $226.7 million Yves Saint Laurent and Pierre Bergé sale in Paris in 2009. He is also known for working with new clients in Russia as well as institutional clients in the Middle East. During his tenure at Christie's, Seydoux was responsible for the Private Sales Department, securing numerous international transactions in his field of expertise.

Academically, Seydoux has written numerous articles on the art market and regularly gives lectures in his field. Notably, he was nominated for the 2012 Alberto et Annette Giacometti Award for his lecture on Infamous fakes and forgeries in the 20th Century.


Thomas Seydoux was raised in France, Italy, and in the United States where he majored in Art History (BA, Dickinson College, Carlisle PA, cum laude) in 1988 and then received a Master's Degree from the University of Pennsylvania. In 1988, he did an undergraduate internship at the Metropolitan Museum on the Jacques and Natasha Gelman Collection and the following year, a graduate internship at the Guggenheim working on the Mario Merz retrospective.

Both of Swiss and French nationality, Seydoux has one daughter, is a passionate runner, and an avid collector of Porsche cars from the Sixties. He is fluent in English, French, and Italian.
