The following accumulation of information concerns the touching history of works by Daumier, which had either been stolen from Museums or private collections or lost over the years and are thus considered missing. Any distinction between stolen and lost works of Art has become exceedingly fragile due to the lack of reliable information caused by two World Wars. The lists presented here will in all likelihood never be permanent but they will be adjusted over time. It should be noted that in a number of cases dating back to the late 1800s no photographs were available, which made it speculative to add these paintings to the list of missing works. In view of the convincing provenance, however, we decided to add them to the list. Any information about missing Daumier works should be forwarded to the Daumier Register in full confidence. Since we are constantly updating data please consult the Daumier Register under the respective DR-number or go to Present location unknown/lost/stolen.
