Abstract
ACCORDING to a brief announcement in Die Chemie of October 28, 1944, Dr. E. C. Wiersma died at Delft at the age of forty-two. He was known for his work at the Kamerlingh Onnes Low Temperature Research Laboratories at Leyden. Both independently and in collaboration with Dr. W. J. de Haas, Wiersma had published a number of papers on the influence of low temperatures on the paramagnetism of certain metals and salts. He studied the adiabatic cooling of magnetic bodies and the production of low temperatures by adiabatic demagnetization. In 1931 he published a classification of para-magnetic atoms, molecules and ions based upon their fields at low temperatures. He also deduced a thermodynamic scale for temperatures below 1° Abs.
