This research verifies the connections between constructive arts and industries after the 1950 s. Particularly, the work aims to inquire the productions and the academic trajectories of two important members of the Brazilian Constructive Vanguard – Décio Pignatari and Lygia Pape. Both of them were artists, designers and professors. In their view, the modern artist should contribute to industrial society in many different ways, because all creative activities were related. As college members, they began teaching semiotics. Lately, Pignatari dedicated his career to literature and communication theories and Pape became interested in visual linguistics education. It is worthwhile to mention that they were educators in graduation and post-graduation courses. Their academic papers discuss the art crisis in the age of mechanical reproduction, proposing ways to overcome this challenge. However, these texts were rarely mentioned as a part of Brazilian Constructive Project. Therefore, this investigation analyses Décio Pignatari s PHD Thesis called Semiótica e Literatura (USP-1973), and Lygia Pape s Masters Dissertation untitled Catiti-Catiti, na terra dos brasis (UFRJ-1980). Initially, their arguments lead to the questioning of the beauty concept as a central aesthetic category. In this sense, C. S. Peirce s semiotics impacts Pignatari s thoughts, and M. Merleau-Ponty s phenomenology marcs Pape s ideals. Lately, this work examines their claims for artistic invention, revealing two different perspectives on this concept. Books written by W. Benjamin, M.Bense and M. Pedrosa integrate their theoretical frameworks.
