The "Transistor" which was Invented By Bell Telephone Laboratories in Dec 1947, and was one the the "Greatest" developments of the 20th century. This important discovery and invention, was the start of the semiconductor revolution and which lead us into the modern computer and information age. The name "Transistor" was derived from a combination of words, which were TRANSconductance and varISTOR. Bell Labs had filed for patent (2,524,035) on this "Transistor" invention on June 17, 1948 and was issued a Patent on Oct 3, 1950.

Walter Brattain and John Bardeen had developed and Invented the germanium Point-Contact Transistor, while working at Bell Telephone Laboratories. Walter Brattain had first demonstrated its "New" Transistor Invention on Dec 23rd, 1947, for a team of Bell Labs management personnel and officials. And Bell Labs had officially announced its "New" Transistor Invention at a Press Conference that was held on June 30, 1948.

William Shockley was in charge of the Semiconductor Research Department, but his name was never put on the original "Transistor" patent. But, William Shockley had developed and Invented the germanium Junction Transistor and applied for a patent shortly afterwards, which was an improvement over the original germanium Point-Contact Transistor. Bell Labs had filed for a patent (2,569,347) for this Junction Transistor on June 26, 1948 and was issued a Patent on Sept 25, 1951. And Bell Labs held an official Press Conference on July 4, 1951, for the invention of the "New" Junction Transistor.

And in 1956, all three Bell Labs scientists (William Shockley, Walter Brattain, and John Bardeen) had won the Nobel Prize in physics, for the invention of the "Transistor".
