Until the late 19th century, many physicians believed that most illnesses were related to digestion problems, and recommended a daily intake of biscuits and fruit. Fig rolls were the ideal solution to this advice. They were a locally produced and handmade product until a Philadelphia baker and fig lover, Charles Roser, invented and patented a machine in 1891 which inserted fig paste into a thick pastry dough. F.A. Kennedy Steam Bakery in Cambridge, MA, is where the Fig Newton, named after the nearby town of Newton was first conceived and produced in 1891.
The Kennedy Biscuit Company had become associated with the New York Biscuit Company, and the two merged to form Nabisco, after which, the fig rolls were trademarked as "Fig Newtons". Since 2012, the "Fig" has been dropped from the product name. They are now just named "Newtons."
