This is a new series Esteve Foundation Notebooks, where we want to edit several activities organized by the Esteve Foundation with different format and languages. In the first volume -published in Catalan-, there is a compilation about medical eponymous from Catalan authors. The original articles were previously published by Josep-Eladi Baños (Department of Experimental and Health Sciences, Univ. Pompeu Fabra, Barcelona) and Elena Guardiola (R&D Department, Bayer S. A., Barcelona) in Annals de Medicina (a Catalan journal edited in Barcelona).
