Liesegang Prize


Raphael Eduard Liesegang (1.11.1869 - 13.11.1947) was a German chemist, who studied in Freiburg but did not finish his academic education. Although not successful at the university, he published already as a student many scientific articles, for instance, about light sensitive organic silver salts. At the same time, he also wrote a book on basic problems of electric television. Liesegang started his career in the factory of his father, who manufactured products for photographic applications. Liesegang invented new light-sensitive papers and developed chemical compounds. In 1896 he discovered periodic precipitations in gels and he observed ordered structures, which were later denoted as "Liesegang rings" (dissipative structures). After the death of his father, he sold a part of his factory, which became one of the origins of the Agfa Company. During the next years, Liesegang worked in different academic positions, for instance, in a museum, a hospital, a paper factory, and an institute of biophysics and colloid chemistry. The extensive work of Raphael Liesegang is published in more than 500 scientific articles and 13,000 short notes (letters). He edited more than 50 books. In addition, he wrote 14 theater dramas!

The Liesegang Prize is awarded to honor outstanding achievements in the area of pure or applied colloid science. The prize is reserved to scientists at an age of about 40-55 years in the midst of their career. The prize consists of a certificate and a memorial coin.
