LAKEWOOD, CO, SEPTEMBER 22, 2003–Kellen Szumski , 1, suffers through a “brain freeze” while enjoying a free 5 oz. Dairy Queen ice cream cone with his brother, Hogan , 3, at 245 South Wadsworth Blvd. on Monday. Dairy Queen was giving away free cones to commemorate the 100th anniversary of the ice cream cone. According to the Dairy Queen website, Italo Marchiony, the legally credited inventor, originally used paper to wrap ice cream in, but later used a pastry and applied for a patent for a cone-shaped mold on Sept. 22, 1903. A similar creation was introduced by Enest Hamwi at the 1904 World’s Fair in St. Louis. The Szumski brothers also have a famous ice cream inventor in their family. Their great grandfather, George Goetz , is credited with inventing the Dairy Queen Mr. Misty at their headquarters in Minneapolis, MN, in the 1960’s, according to Mark Szumski , 39 , the boys’ father. “I remember peering in the window at the (Dairy Queen) labs when I was a kid and watching my grandfather and others working. They’d see us and bring out free ice cream cones,” remembers Szumski. Szumski admitted the Mr. Misty family connection has never yielded a free cone for himself outside of the labs, except for on Monday when he rode to the store with this boys on his way to an errand in Lakewood.
