Sweet'n Low (traemarked as Sweet'N Low) is a popular brand of artificial sweetener from granulated Saccharin, dextrose and cream of tartar. It was invented and first introduced in 1957 by Benjamin Eisenstadt and his son, Marvin Eisenstadt. The elder Eisenstadt had earlier invented the sugar packet, but neglected to patent it, and artificial sweetener packets were an outgrowth of that business. The two were the first to market and distribute the sugar substitute in powdered form. Their distribution company, Cumberland Packing Corporation, still controls the product. The name "Sweet'n Low" itself derives from an 1863 song by Joseph Barnby, which took both its title and lyrics from an Alfred Lord Tennyson poem, entitled The Princess: Sweet and Low. From the 1950s to the 1980s, Sweet'n Low held a virtual monopoly of the artificial sweetener market. Currently, according to Rich Cohen's book Sweet and Low, it holds the #3 position in said market, behind Equal sweetener and Splenda.
