Hans Leo Hassler (1564-1612)

...flourished in the period that bridged the Renaissance and the Baroque.  He was a German who studied in Italy with Andrea Gabrieli, adapted the Venetian style to the German Lied, and created a strong German musical style.  He wrote in all the current vocal and keyboard forms, both Renaissance and early Baroque, but was best known for his settings of German polyphonic songs and chorales.
