International Symposium on Essential Oils
A global scientific community dedicated to essential oils, natural products and aroma science since 1969.
About ISEO
The idea for an International Symposium on Essential Oils (ISEO) was initiated in 1968 at a GA meeting in Würzburg, Germany, during discussions by Professor Anders Baerheim Svendsen, Karl-Heinz Kubeczka, Friedrich Wilhelm Hefendehl and Dr. Jan Karlsen. It was proposed to hold a discussion group on all aspects of essential oils (terpene separation, chemistry, chemotaxonomy or other relevant topics regarding the constituents of essential oils).
In 1969, an informal meeting was organized by F. W. Hefendehl (University of Freiburg, FRG) and K.-H. Kubeczka (Technical University of Karlsruhe, FRG). Dr. J. Karlsen and Professor A. Baerheim Svendsen (both Leiden University, The Netherlands).
The first symposia, organized from 1971 to about 1980, were called Symposium Ätherische Öle, and were later changed to the International Symposium on Essential Oils (ISEO) by which it is known in the world of essential oil science and profession today.
