Charles Tillotson started Tillotson Construction back in the 1920's. He built wooden grain elevators. He passed away in 1938. He left his business to his two sons (Joe and Mike) and his daughter Mary. Mike was known as R.O. His sons had been working in the elevator construction along side of their father. After Charles died, the sons experiment using reinforced concrete, known as slip-forming.
This created a more substanial structure along with a greater capacity, than the smaller wooden elevators.
After WWII, the need for grain elevators exploded. The newer slip-forming construction made the task building elevators a easier method. They was an expansion within the agricultural industry that more and more elevators were needed.
Joe and R.O. had a disagreement. Joe moved to Denver and he started his own grain elevator contruction business. It was originally know as the J.L. Tillotson Construction Company/Denver.
However, everything that I have seen has shown Tillotson Construction Company/Denver, CO.
Between the two Tillotson companies, they have built hundreds if not thousands elevators throughout the mid-west.
I will have a seperate gallery covering the Tillotson Construction Company/Denver, CO
