The 1981 M. S. Tswett Chromatography Awards
The M. S. Tswett Chromatography Medals for 1981 were
awarded to Arnaldo Liberti and Robert E. Sievers at the
16th International Symposium on Advances in Chro-
matography, which took place in Barcelona, Spain,
September 28-October 1. The medals recognize the con-
tribution of the two men in the application of chromato-
graphy to the environmental sciences.
Amaldo Liberti studied at the University of Rome where
hewas a Doctorate cum laude in 1939. Later he joined the
University of Minnesota and received an M.S. degree from this university in 1947. He taught at the Universities of
Rome, Messina, and Naples, finally returning to the Uni-
versity of Rome as the head of the Analytical Department. Since 1968, he has also been head of the laboratory of Air Pollution.
Dr. Liberti is the author and co-author of over 200 papers covering various areas of modern methods of analytical
chemistry such as polarography, solution equilibria, ampero-
metric titrations, coulometry, selective ion electrodes,
chromatography, and environmental analysis. In each field
his research activity has received wide recognition. He was
one of the pioneers in gas chromatography where his con- tributions range from the development of coulometry as
a detection device to column technology, isotope separa-
tion, aroma evaluation, and environmental analysis.
Robert E. Sievers graduated from the University of Tulsa in
1956 and received M.S. (1958) and Ph.D. (1960) degrees
from the University of Illinois. He has since been employed
by Monsanto, CO, Cities Service Oil Co., ARCO, and the
Aerospace Research Laboratories and served as Principal
Investigator for the NASA Apollo Lunar Analysis Project.
In 1968-69, Dr. Sievers was a guest professor at the
University of Tubingen. In 1975, hewas appointed Professor
of Chemistry at the University of Colorado and later served
as Chairman of that department. He is presently Director of
the Cooperative Institute for Research in Environmental
Sciences.
Dr. Sievers has authored and co-authored more than 100 journal publications and holds 16 patents. He is the co-
author of a book, Gas Chromatography of Metal Chelates, and the editor of NMR Shift Reagents. Dr. Sievers is the
recipient of several awards recognizing his pioneering research in the development and application of chromato-
graphy to environmental sciences and metal coordination chemistry. He can be credited with helping make chromato- graphy the most important and broadly applicable tool in
environmental analysis.
