Bell Labs Announces TRADIC
March 14, 1955
AT&T Bell Laboratories announces the completion of the first fully transistorized computer, TRADIC. TRADIC, which stood for TRAnsistor DIgital Computer, contained nearly 800 transistors, which replaced the standard vacuum tube and allowed the machine to operate on fewer than 100 watts which was one-twentieth the power required by a comparable vacuum tube computer.
First Use of Word “Photography”
March 14, 1839
Almost exactly 58 years to the day that his father William discovered the planet Uranus, John Herschel presented to the Royal Society his “Note on the Art of Photography, or the application of the Chemical Rays of Light to the purposes of Pictorial Representation.” This is considered the first recorded use of the word “photography”.
John Herschel was a famous English scientist and polymath, doing work as a mathematician, astronomer, chemist, inventor, and experimental photographer. He was also the inventor of the blueprint among his many accomplishments.
