Deletion of Raoul Albert La Roche

Comment: As well as the entry in the Historical Dictionary of Switzerland, there is an article about him called 'Raoul La Roche, Art collector and Builder of the villa "La Rocca" ' in ''Architectura - Zeitschrift fur Geschichte der Baukunst'' (39(2):171-184 · January 2009) https://www.researchgate.net/publication/291710017_Raoul_La_Roche_Art_collector_and_Builder_of_the_villa_La_Rocca (I just noticed this is already in the article as a bare url reference, which does not show how long it is (13 pages), nor where it was published - in a peer-reviewed publication. There are other sources, which are not as long and don't all cover as much information as these two sources, but the nominator appears to be overlooking the point made in : "If the depth of coverage in any given source is not substantial, then multiple independent sources may be combined to demonstrate notability", and the statement in : "Significant coverage is more than a trivial mention, but it does not need to be the main topic of the source material." Paragraphs are definitely more than trivial mentions, and as well as the sources already included, there are additional paragraphs and informative sentences in 'LE CORBUSIER'S CLIENTS AND THEIR PARISIAN HOUSES OF THE 1920s', ''Art History'' (Jun83, Vol. 6 Issue 2, p188-198) http://web.a.ebscohost.com.rp.nla.gov.au/ehost/pdfviewer/pdfviewer?vid=1&sid=14a34738-2ad0-40fb-91c0-aa59a42ae17c%40sdc-v-sessmgr04 and other articles about Le Corbusier and about La Roche's art collection. He may have been written about because he collected art and commissioned Le Corbusier to design a house for him, but he has been written about. AfD is not about the quality of the article - it can easily be improved with more information from these sources, and with more natural English

Comment: few of the references are about La Roche himself, but about his house or people he knew, therefore  - no particular notability - does not meet  or
