, who laid groundbreaking work in the area of liquid crystal
Liquid crystal
Liquid crystals are a state of matter that have properties between those of a conventional liquid and those of a solid crystal. For instance, an LC may flow like a liquid, but its molecules may be oriented in a crystal-like way. There are many different types of LC phases, which can be...

Career
He received his PhD for his work with the Dr. Wilhelm Maier's liquid crystal group. During that time he completed his ground breaking work on the nematic-isotropic phase tranisition (Maier-Saupe Theory). After his promotion in 1958 he stayed on at the University's Physics Institute and began his work with UV spectroscopic studies on liquid crystals and the method to verify the Frank Elastic constants. In 1961, he transferred to the "Freiburger Institut für Elektrowerkstoffe" and became Maier's research assistant. During this time Saupe began performing NMR studies of liquid crystals. He played a lead role in first discovery of NMR spectroscopy in partially oriented media in 1963, and in a very fundamental paper he was also able to present the essential theory to describe and understand the observable phenomena only one year later. In 1965, after the unexpected death of his mentor Maier, he transferred to the group of Hans-Joachim Cantow at the "Freiburger Institut für Makromolekulare Chemie", that at the time had one of the world's only superconducting NMR spectrometers

, and the following year he became a tenured professor of Physics at Kent State. There he continued his NMR studies, concentrating on the chiral smectic phases and the elastic characteristics of nematic liquid crystals. Saupe retired from Kent State University in 1992 and became the director of the "Max-Planck-Arbeitsgruppe Flüssigkristalline Systeme" at the University of Halle, Germany. He spent his final years, when he was ill of Parkinsons, back in his home town of Badenweiler.
For his work he received the Nernst Prize in 1974, the Humboldt Prize

In commemoration of Dr. Alfred Saupe, The German Liquid Crystal Society began awarding the Alfred Saupe prize to outstanding individuals from all areas of research and technology involving liquid crystals and mesophases.
