The following biographical information is taken from William Thomson's translator's preface to Lipp's Consonance and Dissonance in Music (p. vii):
"A serious student of theology, philosophy, mathematics, natural science, and psychology, his education was as emaculate as it was broad. But he had a creative bent too. His concept of empathetic behavior, though distilled and diluted from years of wear, remains a part of our conventional wisdom about interactive behavior.
"He took his Ph.D. at the University of Leipzig under a giant of early formal psychology -- arguably the Father of modern experimental psychology -- Wilhelm Wundt. He taught at the best universities (Bonn, Breslau, and finally, Munich, where in 1894 he replaced Stumpf as head of the university psychology department). He produced monumental books, monographs, and articles, all among the respected intellectual products of their time.
"Born in 1851, his professional career was wedged between those of older pathbreakers such as Wundt and younger ones who would establish the dominating "schools" of the century, Behaviorism's John B. Watson in the U.S., Gestalt theory's Krüger in Leipzig, Wertheimer, Koffka and Köhler in Frankfurt. His relatively brief life ended not long after World War I had begun, in 1914."
In 1995, the 2nd (1905) edition of Lipp's seminal work Psychologische Studien was translated by William Thomson and published by Everett Books as Consonance and Dissonance in Music.
