Life.
Heinz Kratochwil was born in Mödling a short distance to the south of Vienna. He graduated with a teaching qualification in 1955 from the Faculty of German Studies at the University of Vienna and was then, till 1961, a student of composition at the city's University of Music and Performing Arts ("Universität für Musik und darstellende Kunst Wien") where his teachers included Alfred Uhl and Othmar Steinbauer.
He started teaching at the University of Music and Performing Arts in 1962, teaching harmony and, from 1969, composition. He was appointed Professor of Composition ("Professor für Tonsatz") in 1980. 
Most of his published compositions date from the final two decades of his life. His compositions blended elements of late romantic, impressionist, twelve-tone and jazz styles. 
A highlight, published in 1987, was his first "opera" (described as a "church opera" / "Kirchenoper"), "Franziskus" (op. 161), a setting lasting approximately 75 minutes, using a libretto by Herbert Vogg , and concerned with the life of St. Francis. The first performance took place at the appropriately futuristic Wotruba Church on the western fringe of Vienna only in 1999, however, several years after the composer's death.
