Hammacher attaches great importance to a scholarly opening up of the collection and is surprised that there is little attention for this in the Dutch museums. According to him, the Rijksmuseum Kröller-Müller also ‘has very little to offer […] in the way of catalogues, publications, images. Opportunities to study, also for foreigners, who want to see the unexhibited section, did not and do not exist’. In 1951 he appoints Ellen Joosten, a Master in Dutch linguistics, as his scholarly assistant. Joosten is instructed to ‘make [the collection] public through detailed catalogues’. In late 1952, the first catalogue dedicated entirely to sculpture is published, in which 310 sculptures are described, from Helene’s Asian Buddhas to Hammacher’s latest acquisitions.
