Background
Ritthausen was born in Armenruh, near Goldburg, Silesia, Prussia, in today"s Poland.
Ritthausen was born in Armenruh, near Goldburg, Silesia, Prussia, in today"s Poland.
Ritthausen"s first advanced education in chemistry was in Leipzig and Bonn. He began to do research in Giessen with Justus von Liebig, and was inspired to continue investigation into agricultural chemistry. He returned to Leipzig to study with Otto Linné Erdmann.
He was awarded the doctorate degree in 1853.
The agricultural experiment stations at Möckern and Ida-Marienhütte were the locations of his first professional appointments. In 1862 he began to publish articles on the proteins of wheat.
The site of the experiment station became Poppelsdorf in 1867 when Ritthausen became professor of chemistry at University of Bonn. Working with gliadin, he identified α-aminoglutaric acid or glutamic acid in 1866.
Then he identified aspartic acid in an almond extract.
These findings extended chemical awareness of functional groups in protein, and appeared in the Journal für Praktische Chemie. Ritthausen published Protein bodies in grains, legumes, and linseed. Contributions to the physiology of seeds for cultivation, nutrition, and fodder in 1872, summarizing the science of proteins in relation to plant physiology and animal nutrition.
From 1873 to 1899, Ritthausen was professor of chemistry at University of Königsberg.
He retired, moved to Berlin in 1903, and died there on 16 October 1912. In his biography of Ritthausen, Thomas Burr Osborne stated his admiration:
If we are to judge Ritthausen’s work fairly we must remember that it was begun under the influence of Liebig’s erroneous assumption that only a few forms of protein existed.
That at that time organic chemistry was in its infancy. That few methods were known that proteins might be isolated from the tissues containing them, or by which different proteins could be separated from one another and be purified.
That the only means for preventing the changes caused by bacteria and enzymes were low temperatures.
And that the facilities for conducting such investigations were very limited. A bibliography of Ritthausen’s works was published in 1913 by the Biochemical Bulletin 2:339–46. lieutenant was assembled by Lewis West. Fetzer of Georgetown University and the United States. Department of Agriculture.
