eorge Stephenson was an English engineer and
principal inventor of the railroad locomotive.
Stephenson was the son of a mechanic who operated a
Newcomen atmospheric-steam engine that was used to
pump out a coal mine at Newcastle upon Tyne. The boy
went to work at an early age and without formal schooling;
by age 19 he was operating a Newcomen engine. His
curiosity aroused by the Napoleonic war news, he enrolled
in night school and learned to read and write. He soon
married and, in order to earn extra income, learned to
repair shoes, fix clocks, and cut clothes for miners’ wives,
getting a mechanic friend, the future Sir William Fairbairn,
to take over his engine part-time. His genius with steam
engines, however, presently won him the post of engine
wright (chief mechanic) at Killingworth colliery.
Stephenson’s first wife died, leaving him with a young
son, Robert, whom he sent to a Newcastle school to learn
mathematics; every night when the boy came home, father
and son went over the homework together, both learning.
In 1813 George Stephenson visited a neighbouring colliery
to examine a “steam boiler on wheels” constructed by
John Blenkinsop to haul coal out of the mines. In the belief
that the heavy contraption could not gain traction on
smooth wooden rails, Blenkinsop had given it a ratchet
wheel running on a cogged third rail, an arrangement that
created frequent breakdowns. Stephenson thought he
could do better, and, after conferring with Lord
Ravensworth, the principal owner of Killingworth, he
built the Blucher, an engine that drew eight loaded wagons
carrying 30 tons of coal at 4 miles (6 km) per hour. Not
