At present there are dozens of different brands of a frozen treat made by placing a slab of ice cream between two wafers of chocolate. The original such confection appeared in Iowa in 1920, and its inventer—a candy-store owner named Christian K. Nelson—dubbed it the I-Scream Bar. One year later, this name was changed to Eskimo Pie, on the advice of chocolate manufacturer Russell Stover. Today, Eskimo Pies continue to be made and sold, despite the fact that the word Eskimo is now seen by many as an ethnic slur; in Canada, at least, the term has given way to names that denote the specific peoples of the north, such as Inuit, Inupiaq, and Yupik. The disparagement of Eskimo was prompted by the belief that the name was not chosen by those northern tribes themselves, but rather was an Abenaki term, the Abenaki being a people who lived further south. Worse, the original Abenaki term—askimo—meant eaters of raw meat, and thus had a disparaging connotation. Recently, however, etymologists have begun to question this origin of Eskimo. It now seems more likely that the name derives from a Montagnais phrase pertaining to the lacing of a snowshoe; if this is the case, then Eskimo need not be seen as a derogatory term, which will be a relief to the makers of Eskimo Pie. Incidentally, Eskimo is also the source of esky, an Australian name for a portable cooler used to keep food and drink chilly.
