The 1st working transistor. Yes, it has been preserved.
December 23, 1947: Bell Telephone Laboratories, or Bell Labs for short, announces the invention of the transistor at its headquarters at Murray Hill, in the Township of Berkeley Heights, Union County, New Jersey.
According to Wikipedia:
A transistor is a semiconductor device used to amplify or switch electrical signals and power. The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more are found embedded in integrated circuits...
The first working device to be built was a point-contact transistor invented in 1947 by American physicists John Bardeen and Walter Brattain while working under William Shockley at Bell Labs. The three shared the 1956 Nobel Prize in Physics for their achievement...
Transistors revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things.

In 1963, Shockley went west, teaching at Stanford University between San Francisco and San Jose, leading to the region being known as Silicon Valley, for the element used in most transistors. Sadly, he also began to use his brilliant mind to pass off twisted theories of eugenics. He argued that black people were genetically inferior to white people, and that no amount of social assistance from government would make any difference.
In 1981, a science writer for the Atlanta Constitution compared Shockley's beliefs with the Nazis. Shockley sued for libel. He won the case, and was awarded one dollar in damages. In other words, the damage done was to his ego, for he had already damaged his own reputation with his statements. He died in 1989.
Bardeen won a 2nd Nobel Prize in 1972, with Leon Cooper and John R. Schrieffer, for a fundamental theory of conventional superconductivity. He lived until 1991. Brattain died in 1987.
The court-ordered breakup of AT&T led to the 2007 loss of Bell Labs to the company. The Labs are now run by a competitor, Japanese company Nokia.

December 23, 1947 was a Tuesday. Baseball was out of season. The NFL was leading up to its Championship Game. In the Basketball Association of America, the league that would become the NBA 2 years later, 2 games were played. The New York Knicks lost to the Providence Steamrollers, 66-58 at the Rhode Island Auditorium in Providence. And the Chicago Stags beat the Boston Celtics, 83-75 at the Boston Garden.
Of course, you've heard of the Knicks and the Celtics. In contrast, unless you really know your basketball history, you don't know about the Steamrollers and the Stags -- because they folded in 1949 and 1950, respectively.
One game was played in the NHL, and you'll recognize the names of both teams, even if you're not used to "Black Hawks" being 2 words, as it officially was from 1926 until 1986. The Chicago Black Hawks beat the New York Rangers, 7-1 at the Chicago Stadium. The Hawks got 2 goals each from Metro Prystai and Red Hamill. No, that's not the Moscow subway and a Commie version of Luke Skywalker.
