When Harper and Bowers wanted to expand their grain operation in Estill, S.C., they went with Midwestern expertise. Stiles Harper and Grover Bowers were on the cotton side of things upon founding their company in 1947 but branched out in the early 1950s as South Carolina farmers found success with double cropping. Grain followed by soybeans was a development that sent the producers looking for sufficient storage and handling.
To foster this new practice, Harper and Bowers sponsored a soybean-growing contest. The winners for the 1953 crop were a father-son team, R.C. and Bobby Deloach, the boy being a 4-H club member,. They harvested 36 bushels per acre. Deemed a success, the contest was renewed for 1954.
Stiles Harper was an Estill native who attended the University of South Carolina. He was 37 years old when he cofounded Harper and Bowers, Inc. Besides leading efforts in soybean processing by cofounding Southern Soya Corp., he also advocated for pine tree plantations and was named South Carolina Tree Farmer of the Year in 1977.
Grover Bowers, Jr. was a University of South Carolina graduate who fought with the Marines in the Pacific Theater during World War Two, achieving the rank of captain. He served one term in the South Carolina senate and in 1978 received the Order of the Palmetto, the state’s highest civilian honor.
The first Harper and Bowers elevator, with 125,000-bushels capacity, was built in 1951 by Thomas L. Burrell, Inc. of Indianapolis. Then the partners commissioned Tillotson Construction Co. of Omaha to put up a 225,000-bushel storage annex in 1952.
The next year, Tillotson was back to build a companion elevator, a 334,000-bushel twin-leg job with a striking curved cupola that added 50 additional feet to the Lowcountry skyline. The expansion enabled Harper and Bowers to accommodate the needs of area farmers, a point that’s elaborated in an article from The Press and Standard on Oct. 15, 1953:
A 1954 news report indicated Harper and Bowers planned a storage annex to join the Tillotson elevator, further increasing capacity at Estill to 1 million bushels.
Kristen visited the location in 2014 and took the pictures seen with post.
