was invented in the early 20th century. Archibald Query invented a creation he called Marshmallow Creme in Somerville, Massachusetts, in 1917, while Amory and Emma Curtis of Melrose, Massachusetts, invented Snowflake Marshmallow Creme in 1913. During World War I, Emma Curtis published a recipe for the Liberty Sandwich, which consisted of peanut butter and Snowflake Marshmallow Creme on oat or barley bread. The recipe was published in a promotional booklet sent to Curtis' customers in 1918 and may be the origin of the fluffernutter sandwich. Earlier labels and booklets published by the Curtises suggested combining Snow Flake Marshmallow Creme with peanut butter or eating it on sandwiches with chopped nuts or olives. Meanwhile, sugar shortages during World War I hurt sales of Archibald Query's Marshmallow Creme, so Query sold his recipe in 1920 to two men from Swampscott, Massachusetts, H. Allen Durkee and Fred L. Mower, who began distributing the product through their company, Durkee-Mower Inc. The pair renamed the product Toot Sweet Marshmallow Fluff, and Durkee-Mower continues to sell the product under the name Marshmallow Fluff. The sandwich made with peanut butter and marshmallow creme continued to be eaten, but was not called a fluffernutter until 1960, when an advertising firm Durkee-Mower hired created the term as a more effective way to market the sandwich. Fluffernutter is a registered trademark of Durkee-Mower, although the company's U.S. trademark registrations for the term cover only ice cream and printed recipes. In 2006, Durkee-Mower sued Williams-Sonoma, Inc. in the United States District Court for the District of Massachusetts, alleging that Williams-Sonoma, Inc. infringed on its trademark by selling a marshmallow and peanut butter chocolate-covered candy under the Fluffernutter name. In June 2006, Massachusetts State Senator Jarrett Barrios gained national attention when he proposed legislation restricting the serving of fluffernutter sandwiches in public schools. After Barrios learned that his son was served fluffernutters on a daily basis at his Cambridge, Massachusetts, public elementary school, he created an amendment to a junk food bill that aimed to limit the serving of fluffernutters in Massachusetts public schools to once a week. The proposal was criticized as an example of trivial and overly intrusive legislation, while Barrios' supporters pointed to concerns over the problem of childhood obesity. Among the people who defended the Fluffernutter at the time was Massachusetts State Representative Kathi-Anne Reinstein, whose district in Revere was close to Lynn, where Marshmallow Fluff is made.
