Nobel Prize bond and its application to the structure of complex substances. Pauling was also awarded the Peace Prize in 1962 for his activism against nuclear weapons, making him the only laureate of two unshared prizes. John Bardeen received the Physics Prize twice: in 1956 for the invention of the transistor and in 1972 for the theory of superconductivity. Frederick Sanger received the prize twice in Chemistry: in 1958 for determining the structure of the insulin molecule and in 1980 for inventing a method of determining base sequences in DNA. Two organizations have received the Peace Prize multiple times. The International Committee
Invention of the integrated circuit Committee awarded the Nobel Prize in Physics to Kilby "for his part in the invention of the integrated circuit".

Because of the confidentiality of the Nobel nomination procedure, it is not known whether other IC inventors had been considered. Saxena argued that the contribution of Kilby was pure engineering rather than basic science, and thus his nomination violated the will of Alfred Nobel. The two-inventor version
