History of the transistor about 15 volts". Brattain and H. R. Moore made a demonstration to several of their colleagues and managers at Bell Labs on the afternoon of 23 December 1947, often given as the birth date of the transistor. The "PNP point-contact germanium transistor" operated as a speech amplifier with a power gain of 18 in that trial. In 1956 John Bardeen, Walter Houser Brattain, and William Bradford Shockley were honored with the Nobel Prize in Physics "for their researches on semiconductors and their discovery of the transistor effect". Twelve people are mentioned as directly involved in the invention of the transistor
Committee for the Prize in Economic Sciences in Memory of Alfred Nobel Committee for the Prize in Economic Sciences in Memory of Alfred Nobel The Committee for the Prize in Economic Sciences in Memory of Alfred Nobel is the prize committee for the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, and fills the same role as the Nobel Committees does for the Nobel Prizes. This means that the Committee is responsible for proposing laureates for the Prize. The Committee for the Prize in Economic Sciences in Memory of Alfred Nobel is appointed by the Royal Swedish Academy of Sciences. It usually consists of Swedish professors of economics or
