It's all about the artwork

the documentation process

Every piece of information entered into the catalogue’s database is related to a specific work of art. This includes its characteristics (title, medium, date, dimensions…) as well as information on its current location, provenance, exhibition history, published references, research notes, and more.


The online research platform facilitates the entry and organization of required data around the artwork. The Marchutz catalogue raisonné is powered by panOpticon, a cloud-based information management system, using the Uniform Data Standards recommended by leading members of the Catalogue Raisonné Scholars Association. The panOpticon platform hosts the catalogues raisonnés of over 90 artists, including Paul Cézanne (discover Paul Cézanne’s Catalogue Raisonné), Mary Cassatt, Roy Lichtenstein, Sam Francis and John Singer Sargent.

“One of the many challenges of a catalogue raisonné, is staying focused. When I feel I’m getting dispersed, I repeat to myself my new mantra: It’s all about the artwork.

The mysteries of the catalogue raisonne

Catalogue raisonné research is like detective work. You have to dig, follow leads, gather evidence, compare notes, and build your case. You have to be methodical… and above all, patient. 

A catalogue raisonné is “a comprehensive, annotated listing of all the known works of an artist either in a particular medium or all media”. Sound simple? Well, think again! Like most artists, Leo Marchutz did not keep detailed notes on the artwork he created, exhibited, sold, donated or destroyed. Since research began, we have made some exciting discoveries in a number of museums around the world. We also encountered a fair share of mysteries. Below  is a sample of what we found (or didn’t…)

Leo Marchutz in museums

950 works located in 18 institutions around the world

In the 1930s, Marchutz’s art began to travel the world with the help of John Rewald, who, acting as his agent, brought thirty of his works to London.
Over the following decades, collectors such as Henry Pearlman, James Rosenberg and his benefactor, French architect Fernand Pouillon, continued to promote Marchutz’s artwork around the world. Since 2019, the Léo Marchutz catalogue raisonné project has located over 950 works, notably in museums in North America and in Europe.

“We are delighted to have Mr. Marchutz’s prints in the Museum’s collection. His strength lies in delicacy, in deft suggestion.

 A. Hyatt Mayor
Curator of the Print Department of  The Metropolitan Museum of New York (1959)
