DNA Papers Episode 2: Albrecht Kossel

In episode 2 of the DNA Papers we discuss a cluster of papers from the late nineteenth century by the German physiological chemist Albrecht Kossel, who studied the chemical make-up of nuclein, and found and named its nitrogen-containing building blocks, probably best recognized today by their labels A, T, G, and C. Although work was deemed sufficiently important by his contemporaries to garner him the Nobel Prize in Physiology and Medicine in 1910, Kossel remains a lesser known figure in the history of DNA, especially among non-German speakers. The papers featured in this episode are:

Kossel, Albrecht. 1879. “Ueber Das Nucleïn Der Hefe.” [On the nuclein of yeast] Zeitschrift Für Physiologische Chemie 3: 284–91.
Kossel, Albrecht. 1882. “Zur Chemie Des Zellkerns.” [On the chemistry of the nuclei of cells] Zeitschrift Für Physiologische Chemie 7: 7–22.
Kossel, Albrecht. 1886. “Weitere Beiträge Zur Chemie Des Zellkerns.” [Further contributions on the chemistry of the nuclei of cells] Zeitschrift Für Physiologische Chemie 10: 248–64.
