The professional study of the architects Paquin, Dunant, Mallet, Flores Pirán and Ramos Correa was articulated as far back as 1889 and lasted more than a century, and only ended with the disappearance of Daniel Ramos Correa in 1992. Finally based on multiple archives this book shows an interesting trajectory from the orthodox French academicism of the École des Beaux Arts in Paris to the consolidated exercise of eclectic language that dominates architecture in Argentina during the period.
