Speed defines the world and the professional life of Hans A. Leopold. The Styrian has dedicated himself to precise analog switching, subnanosecond digital switching, and sensors and sensor interfaces. He studied experimental physics at the University of Graz, and in 1971 he went to Aarhus, Denmark, as a visiting professor. In 1984, he became a full professor at the Graz University of Technology, where he was also head of the Institute of Electronics until 2004. Leopold also headed the Institute for Sensor Technology at Joanneum Research between 1980 and 2004.
At the University of Graz, Hans Leopold was a leader in an interdisciplinary group of inventors. The work resulting from this collaboration in the field of precision measurement of density, sound velocity and temperature culminated in numerous patents. Hans Leopold received many awards and was a member of numerous associations such as Senior Member in IEEE. He published 95 papers and holds numerous patents. His inventions in the field of measurement technology are distributed worldwide by the Anton Paar company.
