Arthur Kornberg receives one half of the Nobel Prize for Physiology or Medicine along with Severo Ochoa "for their discovery of the mechanisms in the biological synthesis of ribonucleic acid and deoxyribonucleic acid".

Arthur Kornberg visits Professor H. A. Barker at the University of California at Berkeley.

Arthur Kornberg assumes the chairmanship of the Department of Microbiology of Washington University School of Medicine in St. Louis. In 1953 F.Crick and J. Watson at Cambridge University have just discovered the chemical structure of the DNA molecule. Kornberg's group is now able to build the decoded form of DNA that directs the production of proteins in cells and then they discover the chemical catalyst responsible for the synthesis of DNA.

Arthur Kornberg enrols at the premedical program at City College of New York, where he majors in biology and chemistry in 1937.

Arthur Kornberg dies at 89 at Stanford Hospital from respiratory failure.

Arthur Kornberg enters the University of Rochester School of Medicine. Here he becomes passionate of enzymes—the protein catalysts of chemical reactions.

Arthur Kornberg marries Sylvy Ruth Levy, who is also a biochemist, and who frequently collaborates in her husband's research.

Arthur Kornberg is appointed Professor of Biochemistry and Chairman of the Department of Biochemistry at Stanford University, where he continues his research on DNA biosynthesis with Mehran Goulian. In 1966, Kornberg crafts the first artificial viral DNA. In 1988, Kornberg moves to emeritus status, but he continues to run a lab until his hospitalization.

Arthur Kornberg begins his internship in the University of Rochester 's affiliated institution, Strong Memorial Hospital.

Arthur Kornberg visits Professor Carl Cori at Washington University School of Medicine.

Arthur Kornberg graduates from Abraham Lincoln High School at age fifteen.

Arthur Kornberg discovers deoxyribonucleic acid (DNA) in the common intestinal bacterium Escherichia coli. Kornberg calls it DNA polymerase. Establishing that this enzyme catalyses the production of new DNA strands, Kornberg demonstrates how a single strand of DNA forms new strands of nucleotides, and proves the double helix structure of DNA.

Arthur Kornberg visits Professor Severo Ochoa at New York University School of Medicine. Here he widens his knowledge in enzymology.

Arthur Kornberg is born in Brooklyn to Joseph Kornberg, hardware store worker and his wife, Lena Katz.

After receiving a lieutenant junior grade in the United States Coast Guard, Kornberg serves in the nutrition section of the division of physiology at NIH from 1942 to 1945, then, from 1947 to 1952, as Chief of the division's enzymes and metabolism section. While at NIH, he becomes an authority on the biochemistry of enzymes, including the production of coenzymes. To synthesize these, he uses a condensation reaction, in which phosphate is eliminated from the molecule used to form the enzymes.
