Karl Heinrich Ritthausen (13 January 1826 – 16 October 1912) was a German biochemist who identified two amino acids and made other contributions to the science of plant proteins. Ritthausen was born in Armenruh, near Goldburg, Silesia, Prussia, in today's Poland. 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:

  • Karl Heinrich Leopold Ritthausen (* 13. Januar 1826 in Armenruh bei Goldberg (Schlesien); † 16. Oktober 1912 in Berlin) war ein deutscher Agrikulturchemiker. Ritthausen studierte nach dem Besuch der Freiherrlich von Fletcherschen Lehrerseminars Chemie an der Universität Leipzig, promovierte dort 1853 und war von 1854 bis 1856 an der Landwirtschaftlichen Versuchsstation Möckern tätig. Von 1858 bis 1868 wirkte er als Professor für Agrikulturchemie an der Landwirtschaftlichen Akademie Waldau bei Königsberg und anschließend fünf Jahre lang an der Landwirtschaftlichen Akademie in Bonn Poppelsdorf. Von 1873 bis 1899 lehrte er als ordentlicher Professor für Agrikulturchemie an der Universität Königsberg. Sein wissenschaftliches Interesse galt überwiegend der Eiweißforschung. Die meisten Ergebnisse seiner Experimente veröffentlichte er in den "Berichten der Deutschen Chemischen Gesellschaft". In Königsberg gelang es Ritthausen 1866 erstmals, durch schwefelsauren Aufschluss aus den Kleberproteinen des Getreides, die Aminosäure Glutaminsäure zu isolieren. Die dabei gewonnenen Kristalle übergab er zur weiteren Analyse dem Professor für Chemie in Königsberg Gustav Werther, der daraufhin die Zusammensetzung definieren konnte. Nach Ritthausens Wechsel nach Bonn erfolgte die Strukturaufklärung auf seine Veranlassung hin durch seinen Assistenten, den deutschen Chemiker Wilhelm Dittmar. Ritthausen war Freimaurer und von 1859 bis 1868 Mitglied der Königsberger Loge Zum Todtenkopf und Phoenix. (de)
  • Karl Heinrich Ritthausen (13 January 1826 – 16 October 1912) was a German biochemist who identified two amino acids and made other contributions to the science of plant proteins. 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. While in Bonn he got married. 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. To the writer, who has had a long experience in the same field, under vastly more favorable conditions prevailing a generation later, it is astounding that Ritthausen accomplished so much, and that the data that he secured were in the main so accurate. A bibliography of Ritthausen’s works was published in 1913 by the Biochemical Bulletin 2:339–46. It was assembled by Lewis W. Fetzer of Georgetown University and the U.S. Department of Agriculture.
