Heller László

Managing Real Estate Broker with Fathom Realty PB00068179

Heller László was born in Nagyvárad, Hungary back in 1907.  He received his mechanical engineering degree in 1931 from the Elgenössische Technische Hochschule in Zrichū.  He organized the Department of Energetics at the Budapest University of Technology and Economics, where he worked as a professor.

In 1962, he became a full member of the Hungarian Academy of Sciences.  He died in 1980.

What you may not know about Heller is that he was also an inventor.  In the 1940’s the first high-pressure industrial power station was built according to his plans.  He invented the Indirect Dry Cooling System, which condense the vacuum steam using an injection of cool water.  Using that invention allowed the water to go through a fine-grilled heat exchanger, which cools down the water allowing is to be reused.  That system is still in use and is used all over the world.

Based on the name, I knew he was from Hungary/. The rest of the story was really good too, and what a great invention.  A

Hello James - beyond some obvious names, many(if not most) inventors are not known by me.  Maybe Endre Barath, Jr. has heard of this gentleman.

What Heller László accomplished is beyond my understanding. I guess that is why I pursued a business major and not engineering in college.
