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
Walter Houser Brattain enabler of modern electronics". The three men received the Nobel Prize in Physics in 1956 "for research on semiconductors and the discovery of the transistor effect." Convinced by the 1947 demonstration that a major breakthrough was being made, Bell Laboratories focused intensively on what it now called the "Surface States Project". Initially, strict secrecy was observed. Carefully restricted internal conferences within Bell Labs shared information about the work of Brattain, Bardeen, Shockley and others who were engaged in related research. Patents were registered, recording the invention of the point-contact transistor by Bardeen and Brattain. There was considerable anxiety over whether
