Positive real systems were first discovered and studied in the Networks and Circuits scientific community, by the German scientist Wilhelm Cauer in his 1926 Ph.D. thesis [1–4]. However, the term positive real has been coined by Otto Brune in his 1931 Ph.D. thesis [5, 6], building upon the results of Ronald M. Foster [7] (himself inspired by the work in [8], and we stop the genealogy here). O. Brune was in fact the first to provide a precise definition and characterization of a positive real transfer function (see [6, Theorems II, III, IV, V]).
