Stephen Stepanian, inventor of the concrete mixer

Stephen Stepanian is credited for having invented concrete mixing and transporting vehicle. Stepanian, working in the sphere of construction, discovered several tools and mechanisms to improve the operational efficiency of the construction processes, among which elevator, conveyor, wrench, and sample display holder.

Early in the 1920s, Stepanian was developing plans for a revolutionary piece of equipment to carry concrete from the plant to the job site and keep it mixed en route. It would replace a horse-drawn mixer.

Finally, he summed up his ideas and experience and applied for a patent in 1916. However, the patent was rejected in 1917, because the office did not think track and concrete mixer could be integrated. However, in 1928, Stepanian reapplied for the patent and finally received approval in 1933.

During his life, Stepanian founded and managed several construction companies. In 2004, Stepanian was selected as one of the “Top 100 Transportation Private Sector Professionals” by the American Road and Transportation Builders Association.

P.S regarding the inventions of Stephen Stepanyan there is a good Wikipedia page in English and Russian, but not in Armenian. The generation of Wikipedia pages related to Armenia and Armenians is at a very poor level. This omission competently uses Azerbaijan at the state level, falsifying the history and culture of Armenia in its favor. We will not receive support from the Armenian government. Therefore, it is necessary to do this ourselves on the ground with great activity. Please listen to my opinion and start generating Wikipedia pages, otherwise, we will soon witness rewritten academic sources with splinters of Armenian History.
