Deere, John at English => English (The Britannica Concise) Of Explained:
U.S. inventor and manufacturer of agricultural implements. Born in Rutland, Vt., he was apprenticed to a blacksmith, and later set up his own smithy and moved to Illinois. There he found, through the frequent repairs he had to make, that wood-and-cast-iron plows, used in the E U.S. from the 1820s, were unsuited to the heavy, sticky prairie soils. By 1838 he had sold three newly fashioned plows of his design; by 1846 he had sold about 1,000, and by 1857 10,000. In 1868 Deere & Co. was incorporated, and it gradually began making cultivators and other farm machinery.
