Huntingdon, a borough and the county-seat of Huntingdon county, Pennsylvania, U.S.A., on the Juniata river, about 150 m. E. of Pittsburg, in the S. central part of the state. Pop. (1890) 5729; (1900) 6053 (225 foreign-born); (1910) 6861. It is served by the Pennsylvania and the Huntingdon & Broad Top Mountain railways, the latter running to the Broad Top Mountain coal-fields in the S.W. part of the county. The borough is built on ground sloping gently towards the river, which furnishes valuable water power. The surrounding country is well adapted to agriculture, and abounds in coal, iron, fire clay, limestone and white sand. Huntingdon’s principal manufactures are stationery, flour, knitting-goods, furniture, boilers, radiators and sewer pipe. It is the seat of Juniata College (German Baptist Brethren), opened in 1876 as the Brethren’s Normal School and Collegiate Institute, and rechartered as Juniata College in 1896, and of the State Industrial Reformatory, opened in 1888. Indians (probably Oneidas) settled near the site of Huntingdon, erected here a tall pillar, known as “Standing Stone”; the original was removed by the Indians, but another has been erected by the borough on the same spot. The place was laid out as a town in 1767 under the direction of Dr William Smith (1727-1803), at the time provost of the college of Pennsylvania (afterwards the university of Pennsylvania); and it was named in honour of the countess of Huntingdon, who had contributed liberally toward the maintenance of that institution. It was incorporated as a borough in 1796.
