William Shockley
January 23, 1948:
Shockley's ideas for the junction transistor have finally come together. These lab notes show how the amplifier will work­even how it could be built. The drawing at the bottom of page "a" will come to be used over and over as Shockley describes his idea. Note the horizontal writing in the margin which says: "April 1950 An NPN unit was demonstrated today to Bown, Fisk, Wilson, Morton." Shockley's brain child had finally come to life.
