Benjamin Head Warder (15 November 1824 in Philadelphia, Pennsylvania – 13 January 1894 in Cairo, Egypt) was an American manufacturer of agricultural machinery. In 1902, the company he co-founded merged with four others to form International Harvester.
He was one of the 9 children of Jeremiah Warder (1780-1849) and Ann Aston (1784-1871), Quakers from Philadelphia, Pennsylvania, who had settled in Springfield, Ohio, by the time of the 1830 United States Census. Jeremiah had been a member of his father's shipping firm, John Warder & Sons (later Warder Brothers). John Warder had invested in Ohio land, and bequeathed Jeremiah $10,000 in land.
In 1850 (or 1852), Benjamin co-founded Warder, Brokaw & Child Company, and paid $30,000 for patent rights to "The Champion," a combined reaper & mower invented by William N. Whiteley. Warder's company manufactured the machines, but distribution was shared, at first, with Whiteley and others. By 1860, the Springfield firm was just Warder & Child. In 1866, it was reorganized as Warder, Mitchell & Company, with John J. Glessner and Asa S. Bushnell as junior partners. Senior partner Ross Mitchell retired in 1880, and the firm became Warder, Bushnell & Glessner Company.
It manufactured harvesting machinery – reapers, binders, mowers and hay rakes – under the "Champion" brand name. Warder and Bushnell managed the factories in Springfield, which covered 20 acres. The company opened a branch office in Chicago in 1865, headed by Glessner, which grew to become its most profitable: in 1871, the Chicago office sold about 800 machines; in 1884, it sold 25,000 machines. By 1886, the company employed more than 1000 workers, and was exporting to foreign countries. In 1908, the 2,000,000th Champion machine was sold.
Springfield, Ohio's nickname, "The Champion City," comes from the company's brand name.
Warder retired from business in 1886, and moved his family to Washington, DC, where his house at 1515 K Street NW was under construction. Boston architect Henry Hobson Richardson is credited with the design, but died four months into the project. Richardson's successor firm, Shepley, Rutan and Coolidge, completed the house in 1888. Upon moving to Washington, Warder purchased the late Asa Whitney's country estate of Whitney Close from the heirs of Catherine M. Whitney on June 4, 1886, for the sum of $60,024. He immediately set about subdividing the 43 acre tract of land into building lots for a new community named Whitney Close. This was followed by the subdivision and development of other country properties in the area. These subdivisions—including Whitney Close, Schuetzen Park, and Bellevue—were organized into a single neighborhood known as Park View in 1908. Park View's Warder Street commemorates Warder's role in founding the neighborhood.
