Ivar Giaever (Norwegian: Giæver, IPA: [ˈìːvɑr ˈjèːvər]; born April 5, 1929) is a Norwegian-American engineer and physicist who shared the Nobel Prize in Physics in 1973 with Leo Esaki and Brian Josephson "for their discoveries regarding tunnelling phenomena in solids". Giaever's share of the prize was specifically for his "experimental discoveries regarding tunnelling phenomena in superconductors".
In 1975, he was elected as a member into the National Academy of Engineering for contributions in the discovery and elaboration of electron tunneling into superconductors.
Giaever earned a degree in mechanical engineering from the Norwegian Institute of Technology in Trondheim in 1952. In 1954, he emigrated from Norway to Canada, where he was employed by the Canadian division of General Electric. He moved to the United States four years later, joining General Electric's Corporate Research and Development Center in Schenectady, New York, in 1958. He has lived in Niskayuna, New York, since then, taking up US citizenship in 1964. While working for General Electric, Giaever earned a Ph.D. degree at the Rensselaer Polytechnic Institute in 1964.
The work that led to Giaever's Nobel Prize was performed at General Electric in 1960. Following on Esaki's discovery of electron tunnelling in semiconductors in 1958, Giaever showed that tunnelling also took place in superconductors, demonstrating tunnelling through a very thin layer of oxide surrounded on both sides by metal in a superconducting or normal state. Giaever's experiments demonstrated the existence of an energy gap in superconductors, one of the most important predictions of the BCS theory of superconductivity, which had been developed in 1957. Giaever's experimental demonstration of tunnelling in superconductors stimulated the theoretical physicist Brian Josephson to work on the phenomenon, leading to his prediction of the Josephson effect in 1962. Esaki and Giaever shared half of the 1973 Nobel Prize, and Josephson received the other half.
Giaever's research later in his career was mainly in the field of biophysics. In 1969, he researched biophysics for a year as a fellow at Clare Hall, University of Cambridge, through a Guggenheim Fellowship, and he continued to work in this area after he returned to the US.
In addition to the Nobel Prize, he has also been awarded the Oliver E. Buckley Prize by the American Physical Society in 1965, the Golden Plate Award of the American Academy of Achievement in 1966, and the Zworykin Award by the National Academy of Engineering in 1975.
On 13 September 2011, Giaever resigned from the American Physical Society over its official position. The APS Fellow noted: "In the APS it is ok to discuss whether the mass of the proton changes over time and how a multi-universe behaves, but the evidence of global warming is incontrovertible?"
Giaever married his childhood sweetheart Inger Skramstad in 1952. They have four children: John, Anne, Guri and Trine. Giaever is an atheist.
The Royal Swedish Academy of Sciences has decided to award the 1973 Nobel Prize in Physics to Leo Esaki, USA, Ivar Giaever, USA and Brian D Josephson, UK. The award is for their discoveries regarding tunneling phenomena in solids
The Nobel Prize in Physics 1973 was divided, one half jointly to Leo Esaki and Ivar Giaever "for their experimental discoveries regarding tunneling phenomena in semiconductors and superconductors, respectively" and the other half to Brian David Josephson "for his theoretical predictions of the properties of a supercurrent through a tunnel barrier, in particular those phenomena which are generally known as the Josephson effects".

Dr. Kiminori Itoh, a Japanese environmental physical chemist who contributed to a U.N. climate report, dubs man-made warming "the worst scientific scandal in history." Norway's Ivar Giaever, Nobel Prize winner for physics, decries it as the "new religion."
Nobel Prize Winner for Physics in 1973, Ivar Giaever, a fellow of the American Physical Society, declared himself a dissenter in 2008. "I am a skeptic," Giaever announced in June 2008. "Global warming has become a new religion," Giaever added. "I am Norwegian, should I really worry about a little bit of warming? I am unfortunately becoming an old man. We have heard many similar warnings about the acid rain 30 years ago and the ozone hole 10 years ago or deforestation but the humanity is still around. The ozone hole width has peaked in 1993," he continued. "Moreover, global warming has become a new religion. We frequently hear about the number of scientists who support it. But the number is not important: only whether they are correct is important. We don't really know what the actual effect on the global temperature is. There are better ways to spend the money," he added.
