In 1938 Carl H. Lindner Sr. had an idea to start a small dairy in Norwood, Ohio. At a time when almost all milk was home-delivered and paid for on a weekly or monthly basis, Carl Sr. had a new concept: he would process milk and other dairy products and sell them, cash-and-carry, at his own dairy store. Since he would not extend credit to his customers nor incur delivery costs, he could afford to sell these products at a significant discount versus home delivery.
Carl Sr. and his wife, Clara, had four children: Carl Jr., Robert, Richard and Dorothy. During the Depression the entire family worked together to run several small milk and ice cream companies. Although the children had attended night school to complete their formal education, they received their real education working closely with their father in a succession of dairy enterprises.
This experience led Carl Jr., the eldest son, to run milk delivery routes for Lindner Quality Milk in Mariemont and Beechwood Farms Dairy in Silverton. Robert ran the small milk pasteurizing plant in Mariemont while Richard hauled milk from neighboring country farms to area dairies. Enterprising children, their days started at 4 a.m.
