ICRA Annual Conference 2023: 'On Paper'

5th December
ICRA Annual Conference 2023: 'On Paper'

We are pleased to announce that this year's edition of ICRA's annual conference will be held on Tuesday the 5th of December 2023 at The Royal Academy London.

ICRA’s annual conference this year is titled “On Paper”, and will be dedicated to the question of the relationship between artworks made on or with paper and their classification in a catalogue raisonné. Spanning artistic periods from ancient to contemporary times, we will address questions of how catalogue authors approach different types and uses of paper by painters, sculptors, printmakers, photographers and architects. Material, market and legal issues of conservation and identification of forgeries will be addressed, as well as often difficult methodological decisions that must be made regarding the classifications of sketches, sculptures made out of paper, torn bits of paper, collages, and other contemporary uses of the medium. 

Further information on panels and ticketing is to follow.

Past Events

Visit to the studio of Sir Christopher Le Brun, artist and former President of the Royal Academy of Arts

18th April
Visit to the studio of Sir Christopher Le Brun, artist and former President of the Royal Academy of Arts

Christopher Le Brun is one of the leading British painters of his generation, celebrated internationally since the 1980s. Le Brun employs a mastery of touch and colour alongside a profound understanding of art history and a wide range of visual, musical and literary sources. A heightened awareness of the physicality of the painting process, with its dramatic tension between revealing and covering has been a central feature of his work that unites all its phases, whether abstract or figurative.

He was an instrumental public figure in his role as President of the Royal Academy of Arts in London from 2011 to 2019. He was awarded a Knighthood for services to the Arts in the 2021 New Year Honours. At the beginning of 2023, further two of his major pieces were added to institutional collections of Tate Gallery in London and the Museum of Contemporary Art & Urban Planning (MoCAUP) in Shenzhen.

During the studio visit members met with Christopher and learnt about his methods and practices as an artist as well as his experience as a public figure within the arts.

The ICRA Annual Conference 2022 on Legacy

1st December
The ICRA Annual Conference 2022 on Legacy

ICRA’s 2022 Annual Conference took place at Cromwell Place in London and online on Thursday 1 December from 9.30am (GMT) on the topic of Legacy: The Artist's View. 

This conference had a philosophical construct, placing the artists and their families at the centre of the conversation. The implications of how the catalogue raisonné continues to be perceived proved to be very meaningful.

The keynote speaker was Edmund de Waal with contributions from artists Dame Rachel Whiteread DBE, Sir Michael Craig-Martin CBE RA and Marina Abramovic. There were also conversations between the children of artists, Nick Willing (Paula Rego) and Ben Bowling (Sir Frank Bowling OBE RA), the grandchildren of artists, Saskia Spender (Arshile Gorky) and Daniel Hug (László Moholy-Nagy), as well as others whose work is to shape legacy, including museum curators and catalogue raisonné authors. 

The conference was a hybrid event: held in the Lavery Studio at Cromwell Place in London, it was also filmed and streamed live to a global audience.

This event was generously sponsored by Christie's, Constantine Cannon LLP,, Phillips Fiduciary Services, and Sotheby's.

Private Tour of the Milton Avery Exhibition at the Royal Academy, London

ICRA members were invited to a very special preview of the upcoming exhibition of work by American Colourist Milton Avery, at the Royal Academy of Arts in London. This exclusive event included a tour with the exhibition’s curator, and ICRA Board Member, Edith Devaney and provided ICRA members with a unique opportunity to see this exhibition before it opened to the public. Members also benefited from a personal explanation about the work involved in staging the exhibition as well as insights into the artworks.

From the Royal Academy website:

‘Worshipped by Abstract Expressionists Mark Rothko and Barnett Newman, Milton Avery expressed his vision of the world through harmonious colour and simplified forms. Now, for the first time, see the North American painter’s work this side of the Atlantic’.

Seeing Cezanne

22nd September
Seeing Cezanne

ICRA was delighted to host a webinar with Jayne Warman, co-author of the Cezanne digital catalogue raisonné, entitled ‘Seeing Cezanne’.

The Cezanne online catalogue raisonné, under the direction of Walter Feilchenfeldt, Jayne Warman and David Nash, capitalizes on the versatility of modern-day technology and takes Cezanne research in a new direction. In addition to establishing the authenticity of Cezanne’s pictures, the interactive catalogue provides the researcher a means of studying the works of this influential artist from differing perspectives.

Jayne Warman presented a brief history of the Cezanne catalogue raisonné, demonstrated some of the features of the online edition and outlined some of the challenges faced by her colleagues and the future of their project.

The Launch of International Catalogue Raisonné Association (ICRA)

1st July
The Launch of International Catalogue Raisonné Association (ICRA)

The Academicians’ Room at the Royal Academy was full and buzzing with enthusiasm at the launch of ICRA on Monday 1 July. There was a broad cross-section of people in attendance, many of whom had travelled considerable distances to find out more about the association, its aims and objectives. Board members, Pierre Valentin and Toby Treves addressed the room and were joined by guest speaker Sir Nicholas Serota who gave an excellent speech in support of ICRA stating that its formation was an important and timely venture.

Good catalogues raisonnés transform our understanding of an artist’s work

— Sir Nicholas Serota

We live in an ‘exploded’ world where a sense of belonging is more difficult to achieve than ever before, this is why we need communities of like-minded people and ICRA is exactly that.
