Rudolph Diesel and the Birth of Diesel Power

I've always loved reading biographies. Perhaps it's because every person has a history and it's intriguing to learn about the early influences of people who have later become influential. Rudolf Diesel is one of these.

The name sounds so German you would think he was born in Munich or Heidelberg, but no, he was born in Paris, to German immigrants there, in 1858. A few weeks later he was given away to a farmer family in Vincennes, only to be returned nine months later.

How this experience informed his later development is unknown but when the Franco-Prussian War broke out in 1870 the family was forced to leave France. Why they did not return to Germany but instead went to London is also a curious development. Instead, they sent young Rudolf back to Germany to live with relatives in Augsburg. At age 14 he wrote a letter to his parents saying he wanted to be an engineer.

For what it's worth, this incident reminds me of a joke, if I may digress here. 

What is European Heaven? British humor, French cuisine and German engineering.

What is European Hell? British cuisine, French engineering and German humor.

To verify the facts of these stereotypes, my father wished me to also be an engineer, so while in high school I was encouraged to study German.

Diesel proceeded to study engineering in Munich, where he graduated with honors. His first efforts upon graduation were related to refrigeration, which he pursued with his former professor, now in Paris. After acquiring numerous patents in that field he went on to do research and development on steam engine technology. This ultimately led to the development of an internal combustion engine, since his ultimate goal was the maximum efficient production of power.

Because he understood thermodynamics and the practical limits of fuel efficiency he knew that steam power wastes as much as 90% of the power potential of the fuel. This knowledge is what inspired him to do whatever it would take to develop the engine that now bears his name.

Diesel power is the result of applied science, at the dawn of an emerging scientific era. The first successful Diesel engine, now on display at the German Technical Museum, ran in 1897.

There's little doubt in my mind that Rudolf Diesel would be astonished to see how far his original ideas have been developed and the power supplied by a diesel engine today
