SUBJECT AREA: Metallurgy
b. 26 February 1866 Belleville, Ontario, Canada
d. 15 October 1930 Rochester, Minnesota, USA
American industrial chemist, pioneer manufacturer of magnesium alloys.
Of New England ancestry, his family returned there soon after his birth and later moved to Cleveland, Ohio. In 1884, Dow entered the Case School of Applied Science, graduating in science four years later. His thesis dealt partly with the brines of Ohio, and he was persuaded to present a paper on brine to the meeting of the American Association for he Advancement of Science being held in Cleveland the same year. That entailed visits to collect samples of brines from various localities, and led to the observation that their composition varied, one having a higher lithium content while another was richer in bromine. This study of brines proved to be the basis for his career in industrial chemistry. In 1888 Dow was appointed Professor of Chemistry at the Homeopathic Hospital College in Cleveland, but he continued to work on brine, obtaining a patent in the same year for extracting bromine by blowing air through slightly electrolysed brine. He set up a small company to exploit the process, but it failed; the process was taken up and successfully worked by the Midland Chemical Company in Midland, Michigan. The electrolysis required a direct-current generator which, when it was installed in 1892, was probably the first of its kind in America. Dow next set up a company to produce chlorine by the electrolysis of brine. It moved to Midland in 1896, and the Dow Central Company purchased the Midland Chemical Company in 1900. Its main concern was the manufacture of bleaching powder, but the company continued to grow, based on Dow's steady development of chemical compounds that could be derived from brines. His search for further applications of chlorine led to the making of insecticides and an interest in horticulture. Meanwhile, his experience at the Homeopathic Hospital doubtless fired an interest in pharmaceuticals. One of the substances found in brine was magnesium chloride, and by 1918 magnesium metal was being produced on a small scale by electrolysis. An intensive study of its alloys followed, leading to the large-scale production of these important light-metal alloys, under the name of Dowmetals. Two other "firsts" achieved by the company were the synthetic indigo process and the production of the element iodine in the USA. The Dow company became one of the leading chemical manufacturers in the USA, and at the same time Dow played an active part in public life, serving on many public and education boards.
