RG4106.AM: O.A. Cooper Company (Humboldt, Neb.)
Humboldt, Richardson County, Neb.: Feed and flour mill
Size: 1 box
In 1879, Orrin Alonzo Cooper, J.L. Linn, and L.B. Brinson established a flour mill operation in Humboldt, Nebraska. The original building of this firm, known as Linn, Cooper, and Brinson, was located in the southern portion of town near the Burlington Missouri Depot and cost fifty thousand dollars to construct. A grain elevator also operated in conjunction with the mill. Within a year, Mr. Brinson sold his interest in the company to the other two partners. The new firm of Linn and Cooper remained intact until 1890 when the partnership dissolved. For the next three years, Cooper alone was in charge of the operation. C.M. Linn, son of former co-owner Linn, became Cooper’s new partner in 1893 and remained in that capacity for the next fourteen years. By 1918, O.A. Cooper Company had attained corporate status and within a decade had diversified into mixed feeds. Subsequent growth necessitated acquisition of a feed mill in Beatrice in 1942. Soon thereafter, a new, larger plant and feed mill was constructed in Humboldt in 1944. A feed mill in Cozad was constructed in 1960.
By this time, the O.A. Cooper Company included the following as part of its operations: grain storage, feed and flour milling, and retail sales of various farm and petroleum products. Continued diversification and the need for increased production led to the construction of a more automated mill in South Sioux City in 1967. Two years later, Hammond Mills, Inc. of Oklahoma City became a wholly-owned subsidiary of the Cooper Company. The latter sixth and final feed mill was constructed in 1973-1974 at Abilene, Kansas. During this period, the company further expanded by building liquid feed plants at the Humboldt and Oklahoma City locations. By the late 1970s, the O.A. Cooper Company employed approximately 200 people and distributed its products throughout a ten-state area including Nebraska, Texas and South Dakota. In the summer of 1980, the O.A. Cooper Company fell victim to a takeover bid by the Central Soya Company, Inc. of Indiana.
