George Stephenson was born on June 9th in 1781, he was born in an illiterate and poor family and got a job early in life.
Safe Mining Lamp
In 1815 Stephenson began experimenting with mining lamps because open lamps could be dangerous with flammable gases. by trial and error, he devised a system in which the air entered via tiny holes, and only a month before inventor Humphry Davy submitted his differed design. Stephenson was accused of stealing the design from Davy because he was not seen as an educated scientist.
While Richard Trevithick is credited for designing the first realistic design for a steam locomotive. Stephenson designed his first locomotive in 1814, an engine designed for hauling coal. The engine could haul 30 pounds of coal up a hill at 4 mph, and Stephenson was said to produce 16 of these engines.
George Stephenson was hired to make many other railways, including the first passenger railway as well as other rail engines along with them.
I would not have thought steam engines were as popular as they were back in that time, and as effective as they were. I also think its pretty ridiculous that Stephenson was accused of copying Davy's design, even though they differed greatly.
