   Walter Houser 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.
