Who Was Eldorado Jones?
Eldorado Jones was born in 1860 in Palmyra, Missouri. Her family later moved to St. Louis. Eldorado first worked as a teacher in Lafayette, Indiana. She did not enjoy teaching. So, she became a stenographer, which is someone who types notes quickly, at an insurance company in Chicago.
Early Life and New Ideas
By 1913, Eldorado Jones had started her journey as an inventor. She opened her own factory in Moline, Illinois. This factory was unique because it only employed women. They worked together to make her new inventions.
The Airplane Muffler
One of her most famous inventions was the airplane muffler. She created it in 1919. After some tests at Roosevelt Field, she received a patent for her invention in 1923. A patent means she officially owned the idea.
Time magazine wrote about her muffler. They said that when a plane with her muffler flew, you could hear the propeller and the engine. But you could not hear the loud roar of the exhaust. This meant the muffler worked well.
How the Muffler Worked
In 1931, Popular Science magazine reported that her muffler made planes quieter. It did this without making them lose power. Modern Mechanics and Inventions magazine also called it "the first successful exhaust muffler for airplane engines." The muffler used small spinning parts. These parts "chewed up" the sound waves. They also slowed down the exhaust gases. This stopped the loud noise without hurting the engine's power.
Legacy
Eldorado Jones was known for being very energetic and independent. She was a strong woman who believed in herself. She passed away in 1932.
