The Legacy of Loet Leydesdorff to the Triple Helix as a Theory of Innovation

This paper is an in memoriam tribute to the distinguished scholar Loet Leydesdorff written by some of his academic collaborators, including the editors of the Triple Helix journal and representatives of the Triple Helix Association. The paper revisits Loet Leydesdorff’s seminal contributions and legacy in innovation studies, particularly his work on the Triple Helix model and the measurement of Triple Helix synergies. Additionally, we highlight that Loet was not only a prolific author and outstanding scholar but also a humble person who played a crucial role in the community formed around Triple Helix ideas. The paper also serves as the editorial for the special issue of Triple Helix journal, titled “Legacy of Leydesdorff and the Triple Helix”.
