John DeereBorn 7 Feb 1804; died 17 May 1886 at age 82.American agricultural equipment inventor and pioneer manufacturer. As a blacksmith in a U.S. prairie town, he frequently repaired the wood and cast-iron plows of eastern U.S. design because the local soils were heavy and sticky. By 1838 he had produced three more suitable steel plows of his own new design, and more in following years, which expanded into the agricultural machine business he began upon moving to Moline, Ill. (1847). In another ten years, his annual production had increased ten-fold. Originally using imported English steel instead of cast iron, he converted to U.S. made steel when Pittsburgh steel plants could supply a suitable product. The company diversified with production of harrows, drills, cultivators and wagons.« |
