1839 – First patent issued to Wisconsin resident

On this day Ebenezar G. Whiting of Racine was issued patent #1232 for his improved plow, the first patent issued to someone from Wisconsin. Whiting’s improvements consisted of making the mold-board straight and flat which, when united in the center with the curvilinear part of the mold-board, would require less power to drag through the dirt. Whiting went on to serve as Vice President of the J.I. Case Plow Company and received another patent for a steel plow in 1876. [Source:
