Stefan M. Sarge studied chemistry at the Braunschweig University of Technology. Since 1990 he has worked for the Physikalisch–Technische Bundesanstalt (PTB) in Braunschweig, which is the National Metrology Institute of Germany providing scientific and technical services at the highest level of accuracy and reliability for the benefit of society as a whole, trade and industry, and science.
He is the Head of the Working Group on Caloric Quantities and the author of several publications in the fields of thermal analysis, calorimetry and legal metrology. In 1990 and 2004 he received the Netzsch–GEFTA award.

Günther W. H. Höhne studied chemistry, physics and mathematics at the Technical University of Berlin. In 1997 he was appointed Privatdozent (Adj. Professor) after his habilitation in experimental physics. From 1970 until his retirement in 1999 he was Head of the Section for Calorimetry of the University of Ulm, with duties including academic teaching in physics.
From 1999 to 2008 he was a visiting professor at the Eindhoven University of Technology. He has published numerous articles and two monographs on calorimetry and its applications. In 2002 he received the science award of the German Society of Thermal Analysis (GEFTA).

Wolfgang Hemminger studied physics at the University of Stuttgart and worked for a couple of years at the Braunschweig University in the field of materials science using calorimetry as one tool of research. In 1981 he joined the PTB and worked in the fields of thermal conductivity and various thermoanalytical methods.
In 1989 he was appointed Head of the PTB Division "Thermodynamics and Explosion Protection".
He was co–editor of the journal Thermochimica Acta and is the author of numerous journal articles and books. In 1981 he received the Netzsch–GEFTA award and in 2006 the GEFTA science award.
