This is a homage to Loet Leydesdorff, teacher and scientific reference. Through the combination of overlay maps, a visualization technique proposed by himself and Ismael Ràfols, in combination with the CAMEOs (Characterizations Automatically Made and Edited Online) proposed by Howard White, we project his scientific trajectory in five different scenarios, which turn out to be complementary. For each of the scenarios or CAMEOs, we show how he acts and interacts from the point of view of scientific research, providing the reader with online access to an interactive VOSviewer tool, so that he can check the information presented here, and even go deeper into the analysis we encourage him to do so. To sum up, we can say that Loet was quite a character, a lone wolf who enjoyed working with the best of the best of his main research topics: scientific communication, innovation systems, bibliometrics, and science mapping; becoming, in turn, the referent of these lines of research.
