Fig Newtons were created in 1891 by the Kennedy Biscuit Works in Cambridgeport, Massachusetts. They had named many of their other cookies for nearby towns, and almost called it the "Fig Shrewsbury" before Newton won out.
The following alternate story is from an article in the St. Petersburg Times, 1998:
"The man who originated the Fig Newton, Charles Roser put his cookie recipe to work in his factory in Kenton, Ohio, and sold out to Nabisco in 1910, says Ray Arsenault, in ‘St. Petersburg and the Florida Dream.’”
According to Nabisco: “Fig Newtons were named after either Sir Isaac Newton or the town of Newton, Massachusetts.”
Fig Newtons were one of the first commercially baked products in America.
