David Murray CowieDied 27 Jan 1940 (born 1872). American pediatrician who promoted the iodization of table salt sold in the U.S. to provide a dietary supplement of iodine, thus reducing the incidence of goitre (major swelling of the thyroid gland in the neck.) The value of sodium iodide for this purpose had been determined by David Marine. Cowie, a professor of pediatrics at the University of Michigan gathered support from the Michigan State Medical Society and pursuaded several table salt producers to add 0.01% sodium iodide to their product. Diamond Crystal Salt, and four other companies agreed. On 1 May 1924, the first iodized salt was on Michigan grocers' shelves. Initially reluctant, Morton Salt Company followed suit later in the year for the national market.« |
