About
Hans Leo Hassler (in German, Hans Leo Haßler) (baptized 26 October 1564 – 8 June 1612) was a German composer and organist of the late Renaissance and early Baroque eras, elder brother of composer Jakob Hassler. He was born in Nuremberg and died in Frankfurt am Main.
Hassler was born in Nuremberg and baptized on 26 October 1564, receiving his first instruction in music from his father, the organist Isaak Hassler. In 1584, Hassler became the first of many German composers of the time who went to Italy to continue their studies; he arrived in Venice during the peak of activity of the Venetian school, the composers who wrote in the resplendent polychoral style, which was soon to become popular outside its native city. Hassler was already familiar with some of this music, as numerous prints had circulated in Germany due to the interest of Leonhard Lechner, who was associated with Orlandus Lassus in Munich.
While in Venice, Hassler became friends with Giovanni Gabrieli, with whom he composed a wedding motet for Georg Gruber, a Nuremberg merchant living in Venice, in 1600. Together they studied with Andrea Gabrieli, Giovanni's uncle. Under Andrea, Hassler received instruction in composition and organ playing.
Following Andrea Gabrieli's death, Hassler returned to Germany in the latter part of 1585, moving to Augsburg where he served as an organist to Octavian II Fugger, a nobleman there. The Augsburg years were extremely creative for him; in addition he became well known as a composer and organist at this time, though his influence was limited because he was a Protestant in an area which was still heavily Catholic.
Hassler was not only a composer, but also an active organist and a consultant to organ builders. In 1596, Hassler, along with 53 other organists, was given the opportunity to examine a new instrument with 59 stops at the Schlosskirche, Groningen. Hassler was continually recognized for his expertise in organ design, and was often called upon as the examiner of new instruments. Using his extensive organ background, Hassler stepped into the world of mechanical instrument construction and developed a clockwork organ that was later sold to Emperor Rudolf II.
In 1602, Hassler returned to Nuremberg where he became the Kapellmeister, or director of town music. While there, he was appointed Kaiserlicher Hofdiener in the court of Rudolf II. In 1604, he took a leave of absence and traveled to Ulm, where he was wed to Cordula Claus. Four years later, Hassler moved to Dresden where he served as the electoral chamber organist to the Elector Christian II of Saxony, and eventually as Kapellmeister. By this time, Hassler had already developed the tuberculosis that would claim his life in June 1612. After he died, Michael Praetorius and Heinrich Schütz were appointed in his place.
