Albrecht Kossel was a distinguished German biochemist and an avant-garde in the study of genetics. He was awarded the ‘Nobel Prize for Physiology or Medicine’ in 1910 for his contributions in analysing the chemical composition of one of the genetic substances of biological cells, the nucleic acids. Several techniques were applied by him and his students including hydrolysis to isolate and chemically determine the five organic compounds or nucleobases of nucleic acids as adenine, thymine, guanine, cytosine and uracil. These nucleobases are essential in the formation of the two nucleic acid types, DNA and RNA, the genetic substance present in living cells. He also extensively conducted research on composition of proteins and discovered the amino acid histidine, agmatine and thymic acid. He served as Professor of Physiology and later Director of the ‘Physiological Institute’ at the ‘University of Marburg’. He also became director of the ‘Heidelberg Institute for Protein Investigation’. He was a great influence for his students and also collaborated with some of them namely Henry Drysdale Dakin and Edwin B. Hart, all prominent researchers in biochemistry. He contributed and later edited the ‘Zeitschrift für Physiologische Chemie’, a publication founded by imminent German physiologist and chemist as also his professor cum mentor Felix Hoppe-Seyler.
