Who actually invented the concrete mixer truck? The answer involves rejected patents, immigrant inventors, and a decades-long battle for recognition.
In this documentary, we trace the complete history of the concrete mixer truck — from Richard Bodlaender's horse-drawn "Mortar Mixer" in 1904 to the sophisticated 40,000-pound machines rolling down highways today.
You'll discover the forgotten story of Stephen Stepanian, the Armenian-American inventor who designed the first motorized transit mixer in 1916 — only to have his patent rejected. While he waited, another man got the credit. It would take 17 years before Stepanian finally received his patent, and decades more before he was recognized as the "Father of the Ready-Mix Concrete Industry."
