Act

Egle studied botany in Heidelberg with August Seybold . In 1933 he became a member of the SA . In 1937 Seybold received his doctorate with his dissertation on the knowledge of the light field of the plant and the leaf pigments , which was published in the journal Planta . He then became Seybold's assistant and published with him further work on the dyes involved in photosynthesis, in particular the chlorophylls and carotenes . Together with Hans Fischer he wrote a paper on bacterial chlorophyll. In 1939 Egle became Friedrich Laibach's assistant at the Botanical Institute of the Johann Wolfgang Goethe University in Frankfurt am Main . During the Second World War he was called up for military service in an anti-aircraft unit. In 1943, during a three-month vacation, he was able to complete his habilitation with his research on the resistance of plastid dyes.

Seybold's attempt to bring Egle back to Heidelberg as an assistant in November 1945 failed; he stayed in Frankfurt to rebuild the Botanical Institute under Camill Montfort, which had been destroyed by bombing. In 1949 he was appointed adjunct professor in Frankfurt; In 1950/51 he was visiting professor at the University of Chicago . In 1954 he was appointed full professor for applied botany in Hamburg. From there he returned to Frankfurt in 1959 as head of the Institute for Botany, where he also became director of the Botanical Garden . For the manual of plant physiology published by Wilhelm Ruhland , he wrote the chapters on biogenesis and the biological degradation of chlorophyll, on the "amount and ratio of pigments" as well as the chapters in Volume 5 ("Die CO2-Assimilation", 1960) in accordance with his main research areas the methods of photosynthesis measurement in land plants and for gross and net photosynthesis and photorespiration .

Egle was President of the German Botanical Society in 1966 . In 1967, 1970 and 1973 he served as Treasurer of the International Union of Biological Sciences .
