Some inventions are unrecognized at the time they are created but are later enhanced and to make an impact on the world environment. One such invention created by three scientists working between 1968 and 1971 at TRW in Redondo Beach, California, is an automotive power train for a practical hybrid automobile. Despite the lack of interest by major automotive manufacturers at that time Dr. Baruch Berman, Dr. George H. Gelb and Dr. Neal A. Richardson developed, demonstrated and patented an operable hybrid vehicle system that provided significantly reduced exhaust emissions, outstanding fuel efficiency without sacrificing road performance - long before the hybrid systems in production today.

Many of the engineering concepts incorporated in that first hybrid system are to be found in the Toyota PRIUS, the trailblazer of the current hybrid generation, as well as in vehicles produced or proposed to be produced by Honda, Ford, General Motors and Nissan.The three inventors developed a TRW hybrid power train designated as an electromechanical transmission (EMT) providing brisk vehicle performance with an engine smaller than required by a conventional internal combustion engine drive.

In addition to their pioneering work on the EMT, Drs.Berman, Gelb and Richardson also contributed significant technology to the fields of power systems and processes with developments in advanced batteries, air pollution control, coal conversion, fuel cells and power generation and control.

Dr. Gelb was project manager for the construction and test of the full size EMT system at TRW. He was also active in TRW's programs for advanced space and terrestrial power systems including the evaluation of various systems for land vehicle propulsion such as batteries, fuel cells and alternate liquid fuel systems. He holds five U.S. patents related to energy conversion systems and components. Dr. Gelb is a past member of the Society of Automotive Engineers, American Society of Mechanical Engineers, and the American Institute of Aeronautics and Astronautics.
