Science was the Kornberg family profession that Arthur Kornberg followed. His father, Julius, was a physician and a medical researcher, while his mother, Lena, was a dentist. Kornberg's interest in science was sparked by his father's work, and he went on to become a renowned biochemist and molecular biologist, winning the Nobel Prize in Physiology or Medicine in 1959 for his role in discovering the mechanism of DNA replication.
