Egon Stahl
Egon Peter Gustav Stahl (born October 18, 1924 in Eberbach ; † September 5, 1986 ibid) was a German pharmacist who is considered the nestor of thin-layer chromatography in Germany. He also coined the term “thin layer chromatography”.
Life
Egon Stahl attended elementary and secondary school in Eberbach and from 1937 the secondary school in Karlsruhe . In February 1943 he graduated from high school. Immediately afterwards he was drafted into the Wehrmacht, severely wounded several times on the eastern and western fronts and briefly fell into French captivity, from which he was released in 1945. Egon Stahl began studying pharmacy at the University of Karlsruhe in 1947. In 1950 he passed the state examination and was appointed pharmacist. Also in 1950 he married the pharmacy assistant Liselotte Hemberger.
In August 1952 he was promoted to Dr. rer. nat. PhD. The work entitled “ Investigations into the glandular hairs, the azulene and the essential oil of the yarrow (Achillea millefolium L.) ” was done by Ulrich Weber at the Botanical Institute of the University of Karlsruhe.
From 1954 he was a research assistant in Karlsruhe, having previously managed an assistant position since 1950. In 1954 he spent a few months in the electron microscope laboratory at ETH Zurich with Albert Frey-Wyssling . After his mentor Ulrich Weber died in Karlsruhe, he moved to the Johannes Gutenberg University in Mainz and completed his habilitation at the Pharmaceutical Institute there in 1957 with Hans Rochelmeyer with a work entitled “ About the precursors of chamazulene , their formation in the yarrow glands and their significance ". His habilitation lecture related to his future research field: " Thin-layer chromatography and its application ".
In 1958 he moved to the Botanical Institute of the Saarland University in Saarbrücken, where he qualified as a professor for pharmacognosy and botany . In 1959 he was appointed lecturer, 1961 associate professor and in 1965 finally professor and director of the Institute for Pharmacognosy and Analytical Phytochemistry . He worked at Saarland University until his retirement on October 1, 1985. From 1967 to 1972 he was head of the International Office and the committee for academic international issues. After his retirement he returned to his place of birth Eberbach.
On the occasion of his 60th birthday in 1984, he donated the Egon Stahl Prize , which the Society for Medicinal Plant and Natural Product Research today awards to young scientists in this research area. Scientists receive the Egon Stahl Prize in gold for their life's work in pharmacognosy.
Research areas
His scientific work includes around 200 publications. He devoted himself above all to the research of processes that lead to the formation of essential oils. He developed a process to produce plates for thin layer chromatography in a reproducible manner. He also researched the high pressure extraction of natural substances .
The pharmacist Siegfried Ebel wrote in his obituary for steel: Thin-layer chromatography and his name are nearly synonymus but his work on microthermal migration and supercritical fluid extraction of drugs are also of fundamental importance.
