New York Times Dr. Arthur Kornberg, a biochemist whose Nobel Prize-winning discovery of how DNA is assembled helped ignite the biotechnology revolution, died on Friday in Stanford, Calif. He was 89 and worked in his laboratory at Stanford University until a few days before his death. The cause was respiratory failure, a spokesman for Stanford said.
Dr. Kornberg was one of three Nobel Prize winners who were members of the extraordinary City College of New York class of 1937, including Dr. Herbert A. Hauptman and Dr. Jerome Karle.
Also, he was one of six Nobel laureates whose sons also won Nobel Prizes. In 2006, Roger D. Kornberg was the Nobel chemistry laureate for creating the first pictures of how genes convey messages so that cells can make proteins.
In 1959, Arthur Kornberg was awarded a Nobel Prize in medicine for the discovery of DNA polymerase, an enzyme needed to synthesize the master molecule of heredity.
