Abstract: Tourism Engineering has had times of great development thanks, in part, to the contributions of thinkers around the world. Among the main contributions to this interesting branch of human activity, two cornerstones can be mentioned: The Sábato Triangle and the Triple Helix. The present study intends to clarify the concepts related to these two cornerstones of tourism engineering, especially the interrelations between two impressive contributions to the culture of world tourism. First we will discuss the conceptual work of the Argentine teacher Sábato, and then establish some digressions about the magnificent work of the American thinker Etzkowitz. To conclude, we will establish interrelations that have occurred between two viewing angles for tourism. We will also develop our conclusions on this beautiful subject, and we will propose to the readers some lines of action to make the most of these great ideas, in the daily activities related to tourism professionals, worldwide.
