May 18, 1897: Dow Chemical Founding and Connection to Bleach

May 18, 1897: “The Dow Chemical Company incorporated, based on Dow’s plan to manufacture, sell bleach on commercial scale; 1898 – first commercial scale production of bleach begins; Dow-in-diamond mark created to resolve product shipping problems.”

Commentary: Bleaching powder (or chloride of lime, also known as calcium hypochlorite) was used by Dr. John L. Leal on the Jersey City water supply in 1908. This was the first continuous use of chlorine on a municipal water supply in the U.S.

January 4, 1891: “In 1890, Herbert H. Dow, former college chemistry student at Case School of Applied Science (Cleveland, OH), established Midland Chemical Company in Midland, MI; January 4, 1891 – produced bromine from Midland, Michigan’s rich brine resources (main component of patent medicines at that time) by electrolysis; led to an increasing stream of chemicals from brines; September 28, 1891 – received a patent for a “Process of Extracting Bromine from Natural Brine or Bitter Waters”; “blowing-out” process to liberate bromine from brine; became world’s most efficient bromine manufacturer through application of electrochemistry.”

Commentary: This process marked the beginning of the Dow Chemical Company. The company was formed on May 18, 1897.
