What the Fluff? A Tribute to Union Square Invention
At this stage everyone knows that Marshmallow Fluff was invented in 1917 right here in Union Square. We first celebrated the genius of Fluff creator Archibald Query in a tribute in 2006 on Union Square Plaza in Somerville. Artists, musical and theatrical performers, inventors, and humorists and well over 1000 other people paid yummy homage to this great American foodstuff.
