In Grand Detour, Illinois, blacksmith John Deere hears farmers’ concerns that their plows, designed for sandy soil, aren’t working in thick soil. In response, Deere comes up with a polished board from a broken saw blade. John Deere, blacksmith, evolves into John Deere, manufacturer. Later he recalls building 10 plows in 1839, 75 in 1841, and 100 in 1842. One of the most recognized and longest continuously used logos, the leaping deer trademark has been a symbol of John Deere products for more than 135 years.
