The Symposium on Thermophysical Properties represents a series of conferences that started in 1959 at Purdue University, which at that time was the home of the Thermophysical Properties Research Center (TPRC) founded by Professor Yeram S Touloukian.
A very interesting paper on their history is published as: W.M. Haynes, J.V. Sengers, R.T. Jacobssen and D.G. Friend, “History of the Symposium on Thermophysical Properties”, High Temp. High Press. 34:369-378 (2002).
