Life and work
Christoph Friedrich Hegel Maier was in the seminary in Urach to school and found interest in the species-rich flora of the Swabian Alb. He studied medicine in Tübingen and not as expected by its education would be theology. After his MD thesis in 1857 Hegelmaier worked as a military physician in Ulm. In 1862 he studied in Berlin Botany at Alexander Brown. In 1864 he qualified as a professor in Tübingen and was built in 1867 to associate professor in 1902 was appointed full professor fee. Here he taught and researched in addition to the heads of institutions Hugo von Mohl, Wilhelm Hofmeister, Simon Schwendenerstrasse, Wilhelm Pfeffer and Hermann Vochting Systematic and Applied Botany, later specifically Forest Botany.
Based on Braun's comparative- morphological research direction Hegelmaier has these supplemented by embryological studies. In his " Monograph of the genus Callitriche " (1864 ), he has not only the classification of marked by a greatly reduced flower structure " water star " promoted, but made important contributions especially in terms of histology, development history and lifestyle. He succeeded, among other things, proof of origin of the single terminal stamen of the male flowers. The large monograph on the duckweed plants, " The Lemnaceae " (1868 ), in which he laid down theoretical views on these plant species, was the occasion of a lively discussion. Since then, the knowledge of construction and development of the Lemnaceae as well as the Callitrichaceen were no longer significantly expanded since Hegelmaier.
Basic Hegel were Maiers studies on the development of the embryo of monocots and dicots, as for the construction and development history of the endosperm (partial constriction and obliteration of the embryo sac, convolutive cotyledons, polyembryony and others). The " Comparative studies on development dicotyledonous seeds" (1878 ) include - according to Adolf Engler's judgment - Eduard Strasburger next textbook of botany to the most significant enrichments, which were given to the embryology at that time.
Even in modern teaching and manuals you will encounter exquisite illustrations from Hegel Maiers treatises. His herbarium, which contains in addition to the evidence material to his publications, especially mosses, liverworts, and plants of the repeated he travels the Mediterranean area, forms a valuable part of the museum castle Rosenstein, Stuttgart.
