Gather all the plants of Catalonia. Acquisition of five herbaria from the Institut Botànic de Barcelona through letters from Pius Font i Quer Authors Laura Gavioli Institut Botànic de Barcelona (IBB, CSIC-ICUB) Keywords: herbaria, Font Quer, Cadevall, Trèmols, Vayreda, Salvador, Sennen Abstract In this work we study the role of Pius Font i Quer in the acquisition of the herbaria Cadevall, Trèmols, Vayreda, Salvador and Sennen, analyzing the documents preserved in the archive of the Institut Botànic de Barcelona. We tried to reconstruct the impact that Font i Quer had between 1919 and 1939 in the formation of the herbarium of the Institut Botànic de Barcelona managing and organizing the transfer of these five herbaria. Through the analysis of more than 150 letters and documents, we tried to pinpoint the strategy, policies, tools and personal relations used by Font i Quer. The work is thus able to describe a significant period of the process of professionalization in the management of the herbaria, the different communicative strategies used and the tensions between centre and periphery in the process of institutionalization of science in Catalonia.Key words: herbaria, Font Quer, Cadevall, Trèmols, Vayreda, Salvador, Sennen Downloads PDF (Català) Issue Vol. 12-13 : 2019 Section Awards for Master's Degreee Works in History of Science. 2019 Call License The intellectual property of articles belongs to the respective authors.On submitting articles for publication to the journal Actes d’Història de la Ciència i de la Tècnica, authors accept the following terms:Authors assign to Societat Catalana d’Història de la Ciència i de la Tècnica (a subsidiary of Institut d’Estudis Catalans) the rights of reproduction, communication to the public and distribution of the articles submitted for publication to Actes d’Història de la Ciència i de la Tècnica.Authors answer to Societat Catalana d’Història de la Ciència i de la Tècnica (SCHCT) for the authorship and originality of submitted articles.Authors are responsible for obtaining permission for the reproduction of all graphic material included in articles.SCHCT declines all liability for the possible infringement of intellectual property rights by authors.The contents published in the journal, unless otherwise stated in the text or in the graphic material, are subject to a Creative Commons Attribution-NonCommercial-NoDerivs (by-nc-nd) 3.0 Spain licence, the complete text of which may be found at http://creativecommons.org/licenses/by-nc-nd/3.0/es/deed.en.
