Impressionist and Modern Art

Giovanna Bertazzoni is Vice-Chairman, 20th - 21st Century Department, leading the team of Impressionist and Modern Art Specialists as well as collaborating with the Post-War and Contemporary team to present innovative cross-category sales to the global market.

Giovanna oversaw the Impressionist and Modern Art Department's global expansion in Asia, and was instrumental in selling the first Picasso ever offered in Mainland China, during Christie's inaugural sale in Shanghai in September 2013. Giovanna’s dynamic leadership brought her team to great success in the landmark sale ‘Looking Forward to the Past’ at Christie’s in New York, in May 2015, which saw Les femmes d'Alger (Version 'O'), 1955, by Pablo Picasso set the World Auction Record for Any Work of Art, when it sold for $179,365,000. Giovanna’s international outlook has ensured stellar results are achieved in both London and New York, with particular emphasis on Picasso portraits, such as Femme assise, robe bleue (May 2017, New York) and Femme écrivant (Marie-Thérèse) (June 2017, London).

Giovanna’s passion for works on paper has driven the market for this intimate art form with dedicated sales at Christie’s for 22 years. A personal highlight for Giovanna was the sale of Paul Cézanne’s drawings and watercolours from the Chappuis Barut Collection in June 2003.

In 2020, Giovanna’s creativity and market intelligence were brought together with that of Alex Rotter and together they co-led the implementation of ONE, the first of its kind global relay auction, live-streamed from Christie’s salerooms in Hong Kong, Paris, London and New York. Responding to the need to reimagine the traditional Evening Sale format as a result of the COVID-19 virus, the innovative sale ultimately yielded the highest result for any auction that year.

Giovanna started her career at Christie's in 1998 and has since forged and continues to cultivate strong relationships with a global network of major private collectors, particularly with collectors of works on paper, and graphic arts departments of major European and American museums.

Giovanna lives in London with her husband Andrea and son Martino.

In 2007 Olivier was appointed Head of the London Department, a position he held until 2009. He enjoyed considerable success in this role. In June 2008 the Impressionist Evening sale reached new heights, achieving £144.5m ($285m) thanks to the Miller Collection from Columbus, Indiana - for a long time the highest total for any Impressionist and Modern Art sale in European auction history. In that sale Monet's ‘Nympheas’ sold for £41m ($82m) a world record then not only for Monet, but for any Impressionist painting at auction. He also played a key role in the consignment of single major paintings such as Gauguin's ‘L'homme à la hache’, which sold for the world record price of $40m in New York in November 2006, and Degas' pastel ‘Danseuses à la barre’ which sold for £13.5m ($26.5m) in 2008.

In 2012 Olivier was appointed Deputy Chairman of the department. He has since then been responsible for several major sales such as the Hubertus Wald Charitable Foundation collection from Hamburg, which was a backbone of the London February 2012 evening sales and witnessed several world record prices. In 2014 he was responsible for the sale of the unnamed ‘Modern Masterworks from a Private Swiss Collection’, which included world record masterpieces such as Juan Gris 'La nappe à carreaux' of 1915, which sold for a double world record price of £35m ($57m) as well as Carlo Carra's 'Solitudine' from circa 1917-26, which sold for a record £3m ($5m).

In 2015 Olivier was responsible for the consignment of Picasso's 'Les Femmes d'Alger' of 1955, which sold for $180m, not only beating the previous record price of $108m, but also establishing the world record price for any work of art at auction; he was also responsible for the sale of Mondrian's ‘Composition III’ from 1929, which achieved the new world record of $50m, and the anonymous Belgian collection ‘Reality and Surreality’ which included Bacon's ‘Cardinal Rouge’ and fetched $45m while the total collection sold for $120m (£75m), mostly in February 2015 in London: as well as being responsible for the consignment of the anonymous ‘Figuration and Abstraction: works from a private European collection’, which also sold in February 2015 for £42m ($64m), with Miro’s 1950 ‘Painting (Women, Room, Birds)’ estimated at £4-7m and selling for £15.5 ($25m), a world record for any post-war Miro.

Olivier has been responsible for helping Christie's achieve a dominant position in the Surrealist and Italian 20th Century Art yearly sales in London since their inception in 2000. While Olivier stopped running the Italian sale in 2008, he successfully continues to run ‘The Art of The Surreal sale’ which is world renowned and is the leading sale for such art worldwide and the only one to take place regularly in London every February. As result Christie's holds a 77% market share in that sale format. In 2015 his Surrealist sale achieved a highpoint when Christie’s registered 80% market share against our competitors. That sale at £66.5m ($101m) achieved the highest sold total for any Surrealist sale in auction history.
