Armour, South Dakota

History
Armour was founded in 1885. The city was named after Philip Danforth Armour, who was the founder of Armour and Company, a meat packing company. Contrary to popular belief, Armour was never home to a meat packing plant; the town was so named because Mr. Armour was also the chairman of the railroad that went through Armour and donated a bell to the local congregational church. The athletic teams of Armour High School were formerly known as the "Packers" in reference to the well known packing company, although today the high school plays its sports jointly with Tripp-Delmont High School as the "Armour/Tripp-DelmontNighthawks."
