Ewald Heinrich Rübsaamen
Ewald Heinrich Rübsaamen (born May 20, 1857 in Haardt , Siegen district , † March 17, 1919 in Metternich near Koblenz ) was a German scientist.
Rübsaamen was born as the son of the precision mechanic Franz Rübsaamen and his wife Mathilde, née Franz. He received his education first in the elementary school in Weidenau , later at the secondary school in Siegen , which he graduated with the Abitur.
Following the wishes of his father, the owner of a factory for mining instruments, he began studying mathematics at the technical college in Karlsruhe in 1875 . After four semesters, however, he left university and devoted himself to his artistic vocation with the consent of his parents. He returned to his homeland in Siegerland and trained as a drawing teacher at the teachers' college in Hilchenbach . From 1878 he worked at an elementary school in Steinhauserberg, but in the spring of 1879 he moved to Siegen as head of a private school. During this time, Rübsaamen began an intensive study of botany and zoology as an autodidact. He was particularly interested in plant gall science and research into the gall mosquito family .
After the death of his father in 1891, the entire family moved to Berlin . There he initially worked as a drawing teacher. However, his mother encouraged him to pursue his botanical studies further. He found a job at the Plant Physiological Institute at the Agricultural University. At the same time he attended the Royal Art School from 1892 to 1893, from which he graduated. Nevertheless, Rübsaamen only devoted himself to his botanical interest in the following years. He was employed by Karl August Möbius at the Museum of Natural History without pay and later became his research assistant in the field of entomology . Among other things, he described the plant bile and its pathogens in numerous depictions. On the occasion of the International Horticultural Exhibition in Hamburg in 1897 , where he exhibited more than 100 of his exhibits, he was awarded the Great Golden Merit Medal by the City of Hamburg. From 1909 on, Rübsaamen was the head of state phylloxera control in the Rhineland . In 1912 he was awarded the title of professor by the Ministry of Agriculture and in 1917 he became a member of the Leopoldine-Carolinian Academy of Sciences in Halle (Saale) .
The last years of his life were marked by illness. In addition to heart and lung problems, he also suffered from dropsy . He died on March 17, 1919 at the age of 61.
