Rene Thury (1860 - 1938), a Swiss electrical engineer, was known as the "King of DC" due to his inventions in the field of high voltage Direct Current. transmission. In 1877 , along with his Medical student friend , Jean-Jacques Nussberger , he built a steam powered tri-cycle which operated on coal.
In 1904, it is claimed that Thury developed the first "Parallel Gasoline - Electric Hybrid", where the gasoline engine and electric motor operate on the same shaft. This hybrid vehicle had a range of 40 Kms in pure electric mode with 500 Kgs of battery. The vehicle like the current Toyota Prius , can operate in 3 modes - Pure electric , Pure Gasoline and Mix of both.
Rene Thury continued his career in the electrical engineering field and no more Automotive exploits were recorded.
