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 about 5,000 standard logic ICs, and during their manufacture, the price for an IC dropped from US$1,000 to US$20–30. In this way, NASA and the Pentagon prepared the ground for the non-military IC market. The resistor-transistor logic of first ICs by Fairchild and Texas Instruments was vulnerable to electromagnetic interference, and therefore in 1964 both companies replaced it by the diode-transistor logic [91]. Signetics released the diode-transistor family Utilogic back in 1962, but fell behind Fairchild and Texas Instruments with the expansion of production. Fairchild was the leader in the number of ICs sold in 1961–1965, but Texas Instruments was
