In 1909, George left Ireland to join his brother, Lionel, who had immigrated from England and founded the Cameron Dairy in 1904. Lionel was a pioneer in milk pasteurization and shipped hundreds of gallons to Kansas City daily. In 1909, Lionel started a small ice cream plant adjoining the milk processing facility. Horse carts picked up fresh cream each day from nearby farms. Lionel and George bought the Missouri Dairy of Kansas City and renamed it Chapman Dairy which became a major milk supplier for North Missouri and surrounding states. The Chapman Dairy collected, processed and transported enough milk to fill a passenger train car with ten-gallon milk cans 365 days a year. From Cameron, the milk went to the Chapman Dairy facility in Kansas City where it was delivered throughout the metro area. In 1911, when Lionel accepted a position in Kansas City, George became manager and later owner. In 1927, George’s son, Arthur, known as “Dink”, became a refrigeration engineer. Dink helped install and maintain refrigeration equipment at the ice cream plant and opened his own appliance store in downtown Cameron in 1950. The milk processing plant was discontinued in 1926, but Chapman Ice Cream, the “Cream of Quality”, became increasingly well known throughout the region as an exclusive wholesale firm and it continued until 1970. Dink’s appliance store operated for 25 years.
