O’Neil’s Dairy was first established in 1914 at 115 Kellogg Avenue by brothers Clem J. and P. Henry O’Neil. In 1922, it moved into the building that was formerly the National Guard Armory (today a parking lot across Fifth Street from the Tribune Building). They operated the first commercial milk pasteurizer in Ames. Their specialty was premium ice cream with a high butterfat content, as high as 6 to 7%, marketed as “Velvet” ice cream. It melted in your mouth and clung to your lips.They remained in business for fifty-seven years, closing in 1971.
