The name and nationality of the inventor of the ' CLETRAC ' drive system as used in tracked vehicles.?

Question

The tanks of WW 1 showed poor performance
when steering due to the inherent clumsiness of their simple differential brake setup.
In the mid- 1920 s Cleveland tractor came up with a much more efficient drive and steering system,employing double differentials.
The company called it the 'CLETRAC ' and the patents were issued to Cleveland Tractor.
Still, I assume that one single inventor is possibly the fulcrum of this corporate development.
does anybody have a clue as to this man's name
and - given he was an immigrant - his nationality?

Answer 1

About 4 or 5 years ago, the HISTORY channel did a piece about the tracked vehicles, and tanks in particular, starting with the first world war. There was a segment on the drives and the improvements, and who it was that developed the idea for Cleavland.
But I just did a GOOGLE on "cletrac" and got a load of hits, including WW II vehicles, and several cletrac boards, forums, and restorers. Give it a shot. There might be something there that will lead you to your answer.
