In 1908 – Scottish electrical engineer, Alan Archibald Campbell-Swinton, published a brief letter in the journal Nature, describing the essentials of making and receiving television images. He described using an electron gun in the neck of a cathode-ray tube to shoot electrons toward the flat end of the tube, which was coated with light-emitting phosphor. Others like Farnsworth and Baird would make just such devices years later.

In 2002 – Kevin Warwick had his chip removed. Warwick implanted the chip earlier that year in order to experiment with human-computer interaction, culminating in a direct connection to his wife.

In 2009 – The Lunar Reconnaissance Orbiter (LRO), a NASA robotic spacecraft was launched on its mission to colelct information abotu the Moon, particularly around the poles.

In 1862 – During the US Civil War, W.H. Fancher and C.M. French of Waterloo, New York, received a patent for the “New and Improved Ordnance Plow,” a horse-drawn plow with a gun attached.

In 1936 Edwin Armstrong presented FM radio at FCC headquarters. Armstrong played a jazz record over conventional AM radio, then switched to an FM broadcast. “[I]f the audience of 50 engineers had shut their eyes they would have believed the jazz band was in the same room.”

In 1997 – Programmers deciphered code written in the impenetrable Data Encryption Standard, the strongest legally exportable encryption software in the United States. The hackers organized over the Internet and cracked the software in five months, proving that stronger encryption was needed.

1911 – The Tabulating Company (founded by Herman Hollerith), the Computing Scale Company, and the International Time Recording Company merged to form the Computing-Tabulating-Recording Company in Endicott, New York. They would later change the company name to International Business Machines,and later just IBM.

In 1977 – Software Development Laboratories was incorporated in Redwood Shores, California, by Larry Ellison, Bob Miner and Ed Oates. They later came up with the catchier name, Oracle.

1869, John Wesley Hyatt and Isaiah Hyatt received a U.S. patent for pyroxylin plastic, which they called “Improved Method of Making Solid Collodion” (No. 91,341). The process was slightly flammable, but was essential to the development of plastics.

In 1878 – Photographer Eadweard Muybridge used high-speed photography to capture a horse’s motion. The photos showed the horse with all four feet in the air during some parts of its stride. Stop-motion photography was born.

1822 – Charles Babbage announced his difference engine in a paper to the Royal Astronomical Society entitled “Note on the application of machinery to the computation of astronomical and mathematical tables”.

1941 – John Mauchly visited John Atanasoff in Iowa City to see his computer. The two computer pioneers later battled in court over who was the legal inventor of the electronic digital computer.

In 1951 – The U.S. Census Bureau officially put UNIVAC I into service calling it the world’s first commercial computer.
