History 
In 1873, three families started an oats milling operation originally called the North Star Mill. In 1888 seven of the largest American oat millers united to form the American Cereal Company. In 1906 The American Cereal changed its name to The Quaker Oats Company. On March 7, 1905, an explosion occurred in the mill and much of it was burnt down. At the time the Cedar Rapids Fire Department had no modern fire engines, so many other fire departments in the area sent firemen and fire equipment to help. The main risk was that the fire could spread and burn much of downtown, so the fire engines constantly sprayed water on all the buildings downtown, they kept the fire contained so well that even the neighboring lumber yards were not burnt. There were two casualties, a worker was struck in the head with a flying brick and a first responder went missing during the incident and was presumed dead. The cause of the explosion and resulting fire was said to have been caused by spontaneous combustion. In 1947 the company installed the electric "neon" sign that is atop the main building, since it was erected it has been the largest electric sign in Cedar Rapids. The August 10, 2020 derecho caused major damage to the old neon sign, on June 1 and 2, 2021, the sign was replaced by a nearly identical sign using LED's, but kept the same historic look. On June 7, 2018, a fire was reported at the facility. Employees found that an oven on the 10th floor caused the fire. See also
