E. Remington and Sons (1816-1896) was a manufacturer of firearms and typewriters. Founded in 1816 by Eliphalet Remington in Ilion, New York, on March 1, 1873 it became known for manufacturing the first commercial typewriter. n 1856 the business was expanded to include the manufacture of agricultural implements. Upon Eliphalet's death in 1861, his son, Philo, took over the firm during the Civil War, and diversified the product line to include sewing machines (manufactured from 1870 to 1894) and typewriters (1873), both of which were exhibited at the Centennial Exposition in Philadelphia in 1876. In 1867 Christopher Sholes, Carlos Glidden, and Samuel Lewis invented another typewriter. The Sholes and Glidden typewriter was the first device that allowed an operator to type substantially faster than a person could write by hand. The patent (U.S. 79,265) was sold for $12,000 to Densmore and Yost, who made an agreement with E. Remington and Sons (then famous as a manufacturer of sewing machines), to commercialize what was known as the Sholes and Glidden Type-Writer. Remington started production of their first typewriter on March 1, 1873 in Ilion, New York. The Type-Writer introduced the QWERTY, designed by Sholes, and the success of the follow-up Remington No. 2 of 1878 - the first typewriter to include both upper and lower case letters via a shift key - led to the popularity of the QWERTY layout.
