![]() William Shockley, Bell Labs' team leader and co-recipient of the Nobel Prize with Brattain and Bardeen for the discovery, grew obsessed with the transistor and went on to become the father of Silicon Valley. Crystal Fire fills this gap and carries the story forward. No other devices have been as crucial to modern life as the transistor and the microchip it spawned, but the story of the science and personalities that made these inventions possible has not been fully told until now. The power flowing from the germanium far exceeded what went in in that moment the transistor was invented and the Information Age was born. On December 16, 1947, John Bardeen and Walter Brattain, physicists at Bell Laboratories, jabbed two electrodes into a sliver of germanium. The intriguing history of the transistor its inventors, physics, and stunning impact on society and the economy unfolds here in a richly told tale." Science News "Thoroughly accessible to lay readers as well as the techno-savvy. Here is a deeply human story about the process of invention including the competition and economic aspirations involved all part of the greatest technological explosion in history. Also in 1956, Japan's first transistorized computer, the ETL Mark III, using 130 point-contact transistors and 1800 diodes was built under the direction of Hiroshi Wada at the Electrotechnical Laboratory in Tokyo.On December 16, 1947, John Bardeen and Walter Brattain, physicists at Bell Laboratories, jabbed two electrodes into a sliver of germanium. Led by William Papian, in April 1956 members of the Advanced Development Group of MIT Lincoln Labs used fast germanium switching transistors from Philco Corporation to build a 5 MHz general-purpose digital computer known as TX-0 (Transistor Experimental). ![]() A lighter airborne version (Flyable TRADIC) using junction transistors replaced an analog computer for navigation and bombing control in a C-131 aircraft. Involving about 700 point-contact transistors and over 10,000 diodes, the prototype operated at 1 MHz while requiring less than 100 watts of power. Harris that designed and built a fully transistorized computer dubbed TRADIC (TRAnsistor DIgital Computer) for the U. Felker led a Bell Labs team including engineer James R. The Metropolitan Vickers Electrical Company manufactured six units as the Metrovick 950, which they used commercially within the company from 1956. An enhanced version with 250 junction transistors was completed in 1955. The 48-bit machine used 92 point-contact transistors and 550 diodes fabricated by STC, the UK arm of ITT. Working under Tom Kilburn at Manchester University, Richard Grimsdale and Douglas Webb, demonstrated a prototype transistorized computer on November 16, 1953. ![]() ![]() Operational in April 1950, the National Bureau of Standards Eastern Automatic Computer (SEAC) employed 10,500 germanium diodes and 747 vacuum tubes. By 1960 new designs were fully transistorized. During the 1950s, semiconductor devices gradually replaced vacuum tubes in digital computers.
