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 Invention of the integrated circuit The idea of integrating electronic circuits into a single device was born when the German physicist and engineer developed and patented the first known integrated transistor amplifier in 1949 and the British radio engineer Geoffrey Dummer proposed to integrate a variety of standard electronic components in a monolithic semiconductor crystal in 1952. A year later, Harwick Johnson filed a patent for a prototype integrated circuit (IC). These ideas could not be implemented by the industry in the early 1950s, but a breakthrough came in late 1958. Three people from three U.S. companies solved three fundamental
