Sweet and Low by Richard Cohen bills itself as "the unauthorized true story of one Brooklyn family." And what a family. Cohen, the disinherited grandson of the artificial sweetener Sweet 'n' Low's inventor, combines two parts Horatio Alger-memoir, one part cultural commentary and three parts personal criticism into a fascinating snapshot of American life, immigrant experience and a broad sermon on the perils of fortune. Cohen's maternal grandfather, Ben Eisenstadt, a mid-grade inventor and Brooklyn restaurateur concocts the idea of selling sugar in individual packets--a revolutionary concept in the age of crusty, unsanitary sugar dispensers. His idea stolen by the big sugar companies, Cohen squeaks out a post-war living selling his packets in their shadow until he and his son, Marvin, invent the formula for the saccharine sweetener and catch the first big wave of the American diet craze. Those little pink packets create a vast fortune soon tarnished by interfamily squabbles, Mafia influence, FDA edicts and, mostly, the baser aspects of human nature--greed, jealousy and pride. Cohen, a writer for Rolling Stone and The New Yorker, among other publications, weaves a compelling and often biting narrative about his mother's family. Using those pink packets as metaphor, he paints a dystopic portrait of the American Dream, that, in his family's case, was as devoid of nourishment as any artificial sweetener.--Jeremy Pugh
