Dr. Novak Zuber, who conducted numerous pioneering studies in heat transfer and two-phase flow, was born 100 years ago on December 4, 1922, in Belgrade, the former Yugoslavia. His youth coincided with World War II, during which he served in the Yugoslav Air Force, and after the war, he studied at the University of Rome before becoming a seaman. Unable to abandon his enthusiasm for studying, Dr. Zuber jumped into the sea and smuggled himself into the United States while docking his ship in Los Angeles. After earning his daily bread by washing dishes, washing cars, cleaning chicken coops, and doing yard work, he enrolled at the University of California, Los Angeles. The smooth sailing days did not last long, and when Dr. Zuber was a graduate student, immigration authorities caught Dr. Zuber on suspicion of smuggling. However, university offictals and Congress moved to save Dr. Zuber, a very bright student, and he was granted citizenship. In 1959, Dr. Zuber received his Ph.D. degree with a dissertation entitled "Hydrodynamic Aspects of Boiling Heat Transfer." Chapter 6 of his doctoral dissertation presents a classic theoretical analysis of the boiling critical heat flux from a horizontal plane. The well-known critical heat flux model is now archived in undergraduate-level Heat Transfer textbooks.
