August Wilhelm Eichler, also known under his latinized name, Augustus Guilielmus Eichler (
April 22 1839, in Neukirchen, Hesse– March 2 1887, in Berlin) was a German botanistthat modified former systems to reflect a better relationship between plants. The plant kingdomwas divided into non-floral plants ( Cryptogamae) and floral plants ( Phanerogamae) by him. Eichler Systemis the first one in which the concept of Evolutionwas accepted and therefore it was also the first one to be considered phylogeneticref|Goldberg. Moreover Eichler was the first taxonomist to separate Phanerogamae in Angiospermsand Gymnospermsand the former in Monocotyledonae and Dicotyledonae ref|Lawrence.
Eichler system was the foundation for Adolf Engler's System and it had large acceptance world-wide (mainly in Europe). He studied in
University of Marburg, Germany and was in 1871, professor of Botanyin Technische Hochschule (Technical University), Graz. In 1872 he received an appointment at the University of Kiel, he remained until 1878, when he became director of the herbariumat the University of Berlin.
Eichler made important contributions to the study of the comparative structure of
flowers (mainly on floral symmetryin his work Blütendiagramme).
