He started working with construction of ski jumping hill. Kopfler has designed or been adviser for more than 250 hills. Main designs included all Olympic jumps used between 1960 and 1976, and he even designed one of the reconstructions of Holmenkollbakken in Oslo. He also was the ski jumping technical commissioner for the International Ski Federation. He died of a heart attack at the age of 50. In 1970, Heini-Klopfer-Skiflugschanze in Oberstdorf, one of the world's five ski flying hills, was named for him.^[1]
