On Sept. 4, 2026, musicologist Constantin Floros died in Hamburg, Germany, at the age of 96.

Born in Thessaloniki, Greece, on Jan. 4, 1930, Floros studied law at the University of Thessaloniki from 1947 to 1951 before turning to music, studying composition with Alfred Uhl and conducting with Hans Swarowsky at the Vienna Music Academy. He simultaneously studied musicology with Erich Schenk, as well as art history, philosophy, and psychology, at the University of Vienna, earning his doctorate in 1955 with a dissertation on the composer Carlo Antonio Campioni.

He continued his musicological studies under Heinrich Husmann at the University of Hamburg from 1957 to 1960, completing his Habilitation there in 1961 with a study of the Byzantine kontakion. He became a supernumerary professor at the University of Hamburg in 1967, a full professor of musicology in 1972, and professor emeritus in 1995. In 1999 he received an honorary doctorate from the University of Athens.

Floros served as co-editor of the Hamburger Jahrbuch für Musikwissenschaft and in 1988, founded the Gustav Mahler Vereinigung in Hamburg, serving as its first president from 1988 to 2007 and later as its honorary president. Floros was regarded as one of the world’s foremost Mahler scholars, and his three-volume study of the composer remains a standard reference text in German language Mahler scholarship.

Floros was also elected a member of the Erfurt Akademie der gemeinnützigen Wissenschaften in 1992 and made an honorary member of the Richard Wagner Verband Hamburg in 1999.

His research spanned the origins of Gregorian neumes, Byzantine music, and the connections between Eastern and Western musical traditions in the Middle Ages, as well as the semantic meaning of the symphony in the 18th and 19th centuries. He was noted in particular for pioneering research on the Second Viennese School, including Alban Berg, and on the music of György Ligeti. Among his published works are “Alban Berg: Music as Autobiography,” “Gyoergy Ligeti: Beyond Avant Garde and Postmodernism,” and monographs on Johannes Brahms, Anton Bruckner, and Gustav Mahler.
