Philo was the eldest son of Eliphalet Remington II, blacksmith and inventor of the Remington rifle, and who founded the company of E. Remington & Son. Philo was born and raised in Litchfield, Herkimer County, New York, a few miles southwest of the present town of Ilion, previously known as Morgan’s Landing and as the settlement of New London. Philo was educated in the common schools, and he spent one winter in 1837 in the Seminary at Cazenovia, having become a member of the Methodist Episcopal Church. On his return home, Philo started to work with his father in the mechanical department of the gun works. Around 1841, Philo became a partner in the business, and his younger brothers, Samuel and Eliphalet III became partners in the firm a few years later. Philo was a strong influence in the Remington company’s growth, eventually establishing factories in, and fostering the growth of, Ilion, in Herkimer County. The company won numerous contracts for the production of rifles and pistols, having earned a reputation for superior products. Adding to its success, the company diversified into the manufacture of agricultural tools (1856), sewing machines (1870), typewriters (1874), and other products. In 1865, the company was incorporated, with Philo as president, with his brothers Samuel as vice-president, and Eliphalet as secretary and treasurer. The company’s prosperity was brought down in the 1870s and 1880s by a combination of circumstances that led to various parts of the company being sold off.5, 8, 9
In 1871, Philo, along with an associate Philo Osgood, purchased numerous properties in and around Seattle, Washington, about 200 city lots, for more than $50,000. Their real estate investments, the first by East coast capitalists in the Seattle area, spawned a rumor that the Northern Pacific railroad might locate the railroad terminus at Seattle. The rumor ultimately proved false when Northern Pacific announced in 1873 their decision to build the terminus in Tacoma. Philo’s son-in-law, Watson C. Squire (U.S. Senator and governor of Washington Territory), who was for a time Secretary and Treasurer of the Remington company, exchanged his portion of stock in the company for Philo’s real estate in the Seattle area. Watson eventually cleared farmland and constructed buildings and houses on those properties.5, 9, 10, 11
In 1841 Philo married Caroline A. Lathrop, of Syracuse, who was born in 1825 and died 14 April 1906. They had two children, Ida R. Remington, who married Watson C. Squires; and Ella, who married Howard C. Furman, of New York City. Philo Remington died on 4 April 1889 in Silver Springs, Florida. Public and Methodist church memorial services included resolutions that attested to his noble character of modesty and unselfishness, and as an honorable Christian and a proponent of the temperance cause.9
