Hmmm.... let us see what made the front page of the
July 1, 1948 edition of Murray Hill, New Jersey's, The Madison Eagle newspaper: "Man
Found Dead, Wedged in Drain on Park Edge," "Lawyer Fined $50 on Zone Charge," and Sandra Dean
Stevenson had been born two weeks earlier. Oh, also included was "Invention Replaces Vacuum
Tube" and "Local Man Invents New Device in Electronics for Bell Lab; Could Revolutionize Radio."
Page 10 ran, "Bell Laboratory Releases Data on Newly Invented Transistor."
It is widely known that Drs. Brattain, Shockley, and
Bardeen formerly announced on December 23, 1947, within the walls of Bell Labs in Murray Hills,
their invention of the world's first semiconductor
transistor with a gain of greater than unity. According to a search I
did using my subscription to Newspapers.com,
the earliest instance of a newspaper article about it was July 1, 1948.
says Bell Labs kept the news contained until late June, 1948.
You probably recognize the now-iconic photo of the three inventors gathered around their
transistor in the lab. It is the very first public appearance of the image. Underneath is
"With this apparatus at Bell Telephone laboratories, some of the first investigations leading
to the discovery of the Transistor were made. Seated is Dr. William Shockley, who initiated
and directed the Laboratories' Transistor research program. Standing are Dr. John Bardeen,
left, and Dr. Walter H. Brattain, key scientists in bringing the invention to reality.
The Transistor, Bell Telephone Laboratories' latest contribution to electronics and electrical
communication. Working on an entirely new physical principle discovered by the Laboratories,
the device will serve as an amplifier or an oscillator - perform nearly all the functions
of an ordinary vacuum tube, but involves no vacuum, no glass envelope, no grid, no plate,
no cathode and therefore no warm-up delay. The Transistor has been shown to produce amplification
as high as 100 to 1. Some test models have been operated as amplifiers at frequencies up to
ten million cycles per second."

These items are an archive of past Topical Smorgasbord items that have appeared on the RF Cafe homepage. In keeping with the "cafe"
genre, these tidbits of information are truly a smorgasbord of topics. They all pertain to topics that are related to the general engineering
and science theme of RF Cafe. Note: There is also a huge collection of my 'Factoids' (aka 'Kirt's Cogitations') that might interest you as well.
