Four and a half years after journalist Christopher Latham Sholes received a patent for an invention he called the "Type-Writer," he sold his patent rights for $12,000 to E. Remington and Sons of New York state. An arms manufacturer seeking to diversify, they were a firm well equipped with the machinery and skill to carry out the development work. On March 1, 1873 E. Remington and Sons began the manufacturing of the first practical typewriter in Ilion, New York.

Organic chemist Wallace Carothers began working at the DuPont Experimental Station in 1928. One day, a team of researchers, led by Carothers discovered an molten substance: it would stick to a glass rod and form a fine strand. As soon as the strand met the cold air, it solidified and formed a long continuous fiber that was both flexible and strong. The fiber was stronger and elastic than silk. The first example of what would become nylon was produced on February 28, 1935.

Phoenix, Arizona, became a city on February 25, 1881. At that time it had a population of about 2,500 people. It was Englishman Lord Darrell Duppa, one of the original settlers, who suggested the name "Phoenix". He saw the prehistoric ruins of the native Hohokam people, who had lived on the land for two thousand years, and predicted that another civilization would rise from them, like the mythological fire bird which was born again from its own ash after it died.

Roman emperor Diocletian's first "Edict against the Christians" was published on February 24, 303, beginning the Diocletianic Persecution, the last and most severe episode of the persecution of Christians in the Roman Empire. Diocletian's systematic intense persecution against the Church,  climaxed in early 304 when all Christians were required to make sacrifice to the empire on the pain of death. An estimated 3,000–3,500 Christians were martyred in the persecution.

The Gutenberg Bible was the first major book printed using mass-produced movable type. The traditional date for its publication was February 23, 1455. 42 lines were printed on each of the 1,242 pages in a gothic typeface which was as near as its German inventor, Johannes Gutenberg could get to the handwriting of the day. It was printed on paper made from cloth, rags and vellum.
