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
Heineken Prizes the Dr A. H. Heineken Prize for Art. The Heineken Prizes are awarded in a Special Session of the Royal Netherlands Academy of Arts and Sciences, which takes place every even year at the Beurs van Berlage in Amsterdam. In 2002, 2004, 2006, 2008, 2010 and 2012 the Prizes were presented by HRH the Prince of Orange. The following winners of the Heineken Prizes for Medicine and Biochemistry and Biophysics have since won a Nobel Prize: Heineken Prizes The Heineken Prizes for Arts and Sciences consist of eleven awards biannually bestowed by Royal Netherlands Academy of Arts and Sciences (KNAW).
