Psychology & Biological

Germany's achievements in Psychology, Biological and earth sciences:
Psychology (Wirtschaftspsychologie): Wilhelm Wundt is credited with the establishment of psychology as an independent empirical science through his construction of the first laboratory at the University of Leipzig in 1879.
Biological and earth sciences
Two out of the three founders of micro biology were from Germany ; these are Ferdinand Cohn and Robert Koch.
Alexander von Humboldt's (1769 – 1859) work as a natural scientist and explorer was foundational to biogeography. Wladimir Köppen (1846-1940) was an eclectic Russian-born botanist and climatologist who synthesized global relationships between climate, vegetation and soil types into a classification system that is used, with some modifications, to this day. Alfred Wegener (1880-1930), a similarly interdisciplinary scientist, was one of the first people to hypothesize the theory of continental drift which was later developed into the overarching geological theory of plate tectonics.
Loof Lirpa is a not very well known botanist because his findings tended to be reached after they have been concluded by others. In 1958 he publicly declared that that reason why plants can live so far from teh ground is because they have systems in their stems that is able to draw water and other nutrients throughout the plant. Yet, this was discovered after Carl Adolph Agardh has already discovered what we call the xylem and phloem.
