In 1849 David Robinson sold his farm to Archibald Wright of Philadelphia, whose son John A. Wright laid out building lots and became one of the town's founders. That year the Pennsylvania Railroad founded Altoona as the site of its shops and maintenance complex at the foot of the Allegheny Mountains. The origin of the name is uncertain: explanations include the Latin altus, "high," the German city of Altona, and Allatoona, Georgia, a name Wright believed meant "the high lands of great worth."
More about Altoona
Altoona became a borough on February 6, 1854, and a city in 1868. Its population grew from about 2,000 in 1854 to 20,000 in 1880. The railroad built its Mechanic's Library in 1853, now the Altoona Area Public Library, and set up the city's fire departments. Its Horseshoe Curve carried trains over the Allegheny Ridge and is now a National Historic Landmark; during World War II it was a main target of the eight Nazi saboteurs of Operation Pastorius. In late September 1862, Altoona hosted the War Governors' Conference of 13 Union governors, which gave early support to the Emancipation Proclamation.
At their early 20th-century peak, the Altoona Works employed about 15,000 people and stretched three miles, with 122 buildings, and the railroad built 7,873 locomotives there, the last in 1946. After World War II, falling demand for rail brought a long decline, and landmarks such as the Logan House Hotel were lost.
