George Stephenson

Born 9 Jun 1781; died 12 Aug 1848 at age 67. English engineer and inventor who was a principal pioneer of the railroad locomotive. The first railway he built ran from Darlington to Stockton which opened 27 Sep 1825 when large crowds saw him at the controls of the Locomotion as it pulled 36 wagons filled with sacks of coal and flour. The initial journey of just under 9 miles took two hours. The Rainhill trials of 1829, was a competition for building the fastest locomotive. He won with his famous locomotive, the Rocket, which traveled at an unheard of speed of 36 miles per hour. Stephenson then built the Liverpool to Manchester line which opened on 15 Sep 1830. He is regarded as one of the most influential people of the Industrial Revolution in Europe.
