Transistor
From November 17, 1947, to December 23, 1947, John Bardeen and Walter Brattain at AT&T's Bell Labs in Murray Hill, New Jersey of the United States performed experiments and observed that when two gold point contacts were applied to a crystal of germanium, a signal was produced with the output power greater than the input. Solid State Physics Group leader William Shockley saw the potential in this, and over the next few months worked to greatly expand the knowledge of semiconductors. The term "transistor" was coined by John R. Pierce as a contraction of the term "transresistance". According to Lillian Hoddeson and Vicki Daitch, authors of a biography of John Bardeen, Shockley had proposed that Bell Labs' first patent for a transistor should be based on the field-effect and that he be named as the inventor. Having unearthed Lilienfeld’s patents that went into obscurity years earlier, lawyers at Bell Labs advised against Shockley's proposal because the idea of a field-effect transistor that used an electric field as a "grid" was not new. Instead, what Bardeen, Brattain, and Shockley invented in 1947 was the first point-contact transistor. In acknowledgement of this accomplishment, Shockley, Bardeen, and Brattain were jointly awarded the 1956 Nobel Prize in Physics "for their researches on semiconductors and their discovery of the transistor effect".
Grant O. Gale
From Bardeen, Gale acquired early versions of the transistor. One of Gale's most noted students was his former baby sitter, Robert Noyce, co-inventor of the integrated circuit and founder of Intel. While Noyce was his student at Grinnell:
Gale had kept up with Bardeen and his work, and he obtained two transistors in 1948 while Noyce was an undergraduate. Noyce worked with Gale on the transistor and was thus among the first to encounter its limitless potential.
Gale's mentorship of Noyce was also instrumental in protecting him from disciplinary action when Noyce stole a pig from a nearby farmer (who actually was also the Mayor) and then slaughtered it in Clark Hall for a college luau. The prank would have earned him expulsion and jail time since livestock theft was a felony offense in Iowa, if not for Gale's intervention. (The pig you refer to was actually slaughtered by Roger Barnes, a Hawaiian physics student in the fall of 1966. Mr. Barnes was encouraged and assisted by Richard Weeks of Palatine, Illinois and John Pittman of Lake Oswego, Oregon and elected by his housemates to prepare the feast. He was the only student who had any actual experience preparing a suckling pig for a luau. The festivities were halted when a maintenance man saw the pig hanging from the shower spigot and alerted the Dean of Men. The Dean surprised the assisting group of students who were just on a "study break" and ordered them to stop immediately. They were directed to take the carcass to the Saga Foods Dining Hall where it could be properly disposed of. The partially shaved and scrubbed pig may not have reached its intended destination and actually ended up at Clark Hall, the dormitory adjacent to the Dining Room. Thankfully. It was a cold night.)
